Q 2329: Email me relevant information on Lochabriggs stone. Joe, July 29, Reply
R1: Dear Joe, LOCHARBRIGGS (not LOCHABRIGGS) SANDSTONE, Sandstone is characterized by red or pink colouring, and it is medium grained in texture, free of clay holes and other impurities. The stone is quarried from the outskirts of Dumfries in Scotland. It is a Permian Sandstone. Daniel, SlovakiaQ 2321: Have you heard of a granite called "marron castor"? I am unable to find any information about it. Thanks, Carol, July 28, Reply
R1: Dear Carol,
MARRON CASTOR (BROWN CASTOR, MARROM CASTOR) is granite from
R1: Dear Sir or
Lady, UBATUBA is the Brazilian charnockite from end of the Proterozoic
(about 600 million years). The charnockite is the special rock of granite
or syenite composition in which there are feldspars,
R1: There are
two schools of thoughts about marble:
R2: I am a marble restoration professional who also has over twenty years of experience in the oil industry. I can say without fear of contradiction that most petroleum geologists spend their entire careers trying to answer this question. Very few are consistently successful. Sorry, but I doubt that there are any contributors to this site who can advise you on where to drill your next oil well. Good Luck, Mike, USAR1: Dear Sherry: I don't know if this is because of the fact that English is not my original tongue, but, quite honestly, I have no idea of what you're talking about. Stone releasing oils over time??!! why Could you please elaborate for me? Ciao and good luck, Maurizio, USA
Q 2247: I've got a stone sample from a shop in the UK (though they're not around anymore) with the word 'Gaban' on it. I like the stone, but want to find out more about it. Where can I buy it? Any thoughts? An hour on the web has revealed nothing! July 16, ReplyR1: Dear sir or lady, The GABAN stone is a very strong, pale grey, fresh microcrystalline limestone with some variations in grain size notable by the presence of quartz and/or clay-bearing bands cutting through the material at a shallow angle to the bedding. It is product of stone quarries in England. Daniel, Slovakia
Q 2241: Please inform if you do know anything about the following types or names of stone and marble, or are they fantasy names. In the past twenty years of my experience in this field I have seen many alternative names given to natural stones. Could this be the same case? MEUCHATEL MARBLE, MARILU STONE, GREEN ROMINA MARBLE. I hope to receive any information that can be useful. Farah, UAE, July 15. ReplyR1: Dear Farah, I think MEUCHATEL is distortion from NEUCHATEL. Some limestones for building purposes were quarried near Neuchatel lake in Swiss. I have never heard of MARILU STONE or ROMINA MARBLE, only of MALIBU migmatite from India. Daniel, Slovakia
Q 2230: What is pinola stone & therma stone? Janet, July 15, ContactR1: Dear Janet, PINOLA STONE or Pine Stone comes from Georgia, USA. This probably calcareous sandstone has a white background with blends of caramel, purple, red, and blue all mixed throughout. This type for stone can be used as a stack stone, veneer, for patio, walkway flagstone, landscape stone, or for a water feature environment, and also for interiors. I have never heard of THERMA STONE. Therma floor is a gypsum under layment designed to pour over hot water tubes or electric heating cables. Daniel, Slovakia
A 2131: I have chosen a granite that the local supplier identifies as Verde Butterfly Canadian -- it doesn't have the white like "Verde Butterfly" - it has more yellow, plus there are some red stone chunks that look like garnet.
It's a beautiful stone, but they may not have enough slab to do my entire kitchen and they probably will not be able to obtain more stone. The island is huge and I would prefer slab for that, and would be willing to compromise on back counters.
So, my questions are:
Do you have any suggestions for a complementary surface if they can only do the island with the slab?
Do you have any suggestions on obtaining more of this stone, or how I could find out if anyone out there has tiles of the same stone (I would be willing to use granite tiles on the back countertops)?
I'm located in Boise, ID if you have any suggestions that would help me out, they would be greatly appreciated. Killee, June 28. Reply

A 2061: Please help me with any information available of the stone called Valentino Semi Classico, it have any other name perhaps? Thank you, Gio, June 14, ReplyR1: Dear Gio: The only "Semi classico" I know of, is an Italian compact limestone (traded as marble, by the name of Botticino Semi Classico. If that's "your man", it's a beige colored stone, it's quite hard (for a marble) and quite dense, too. It doesn't take a polish uniformly (it shows several natural dead spots -- no crystallization, that is -- that will not polish), like its brethren Botticino Classico does.

I live in central Texas, I was told by one that it was Mexican and another it was from Oklahoma. I am attaching pictures. Thanks for the help! Eric, June 1, ReplyR2: Dear Eric, your samples are the most probably TEXAS CREAM LIMESTONE. Fossil of belemnite is probable on one bed surface. The limestone is probable of Cretaceous age.

A 1981: Recently, I went to a showroom
to choose a granite countertop for my kitchen.
A 1964: I am a newcomer to this arena and I am thinking about buying a granite called Ocean fantasy for a kitchen countertop. I have been to different places and they are mostly gray with white swirls, with considerable variation. Can anyone tell me more about this granite for this use? Robert, May 25, Reply
R2: Dear Robert, OCEAN FANTASY is migmatite (granite gneiss) from Brazil. Such stone type is very changeable, but suitable for the countertop. Daniel, Slovakia
A 1898: Daniel, John, Maurizio, Greetings from a fellow geologist. We just installed a LOT of stunning Juparano Colombo (a remobilized orthogneiss in this case) in our house. Everyone is asking me where it is from- in the geological sense. My fabricator has no idea and what little I can find on the web indicates either Sri Lanka (unlikely), India or Brazil. Not much help there. Of course I know that whereever it came from- it spent some time at what looks to be maybe 6 to 8 kilobars with right lateral shear ;) Gentlemen- I welcome any info you can provide so that I can learn more about this stone- where is it being quarried today, etc.? Thank you, George, May 15. ReplyR2: Dear Geroge, JUPARANA COLOMBO migmatite was originally quarried in Sri-Lanka. Later similar material was found in India (Tamil Nadu, Thogaimalai) and this is now quarried. The rock was formed during the Proterozoic. Daniel, Slovakia,

A 1843: Hi guys- I am a sculptor and a stone carver. Is there a dark or richly veined limestone that is even close in carvability to Indiana Limestone? Thanks- Dale,May 14.Reply
A 1824: Hi- I love the website- loaded with info... I am looking at purchasing granite kitchen countertops and am more confused then ever. How can you tell what is/isnt granite when the sales people are telling u it is granite??? I am looking at Florence Rose and Golden Viara(?). Thank you, Darlene, May 14.ReplyR2: Unfortunately you can't. Many people who sell stone counters wouldn't know what is granite and what is not. Simply stated true geological granites represent 2-3% of the stones used for counters. The granites were used first so most mercantile outlets used that designation to make things simple. Unfortunately again, it confuses rather than simplifies.
The Golden Vyara is a gneiss that is typically resined so it may do just fine in the kitchen. Use the absorption test (lemon juice test) to assess. The other I am not familiar with. That is the second problem there is not a true standardized naming process that appeals to everyone for one reason or another. Regards, Steven, USA,

I can find no mention of mill glass anywhere. Can you help us? Thank you. Sharon, USA, March 7, Reply
R4: Hi Sharon: I use Mill Stone on a regular basis. It is coarse sandstone from the millstone grit series. I assume it is the same in the US as geological terms are pretty much international. All the answers are correct also. I don't know what came first - the name for the stone or it's use in grinding mills. Bryan UK.R3: In the UK, we have a type of sandstone that is referred to as Millstone grit, The particles that make up the stone are often random in size and angular. In fact, it is very suitable as a grinding stone or perhaps a mill stone?? You will need to look in a sandstone area & not a parking lot. Roy. UK
R2: Mill stone is a block of stone which is chiseled round in a radius of 1' feet and the height is about 4". it has a hole in the center. It was used in a hand operated machine for grinding wheat.

A 1456: I have been told that there are several different qualities of "crema marfil". If so, what are they, where does the best stone come from and how do I contact the quarry? Thank you, Gregg, Feb 19. ReplyR2: We have just finished cutting and installing a large bathroom in Crema Marfil so we have got to know it a bit better. Like most stones there are different grades but I am unaware of any distinct classifications. Generally in this marble the more veins it is the easier it will break. Unlike some marbles the minerals in the veins appear to be formed after metamorphism and in the case of this marble are sometimes very weak. A clue to be found on the rear of marble which have low vein strength is that there is often a matrix of fibre glass, jute or the likes, glued on to the back to keep it intact during handling. So you take your pick, ease of use or appearance. On the plus side, if installed correctly, once it is in place these loose veins appear to present no problem and it's appearance can outweigh problems of installation. It also scratches quite easily but they polish out easily. It is quarried in Spain and most wholesalers in Europe stock it and I presume but presume only that many in the US would also. Bryan, UK, Reply
Greg, I don't think you just contact the quarry. Try working with the
dealers in your area first. If your project is large enough to warrant,
take a trip to Italy.

A 1407: I'm in the process of purchasing marble/travertine for my bathroom. I have seen the tiles I would like buy. In one shop they called a terracotta tile Rosa Verona and a cream tile Botticino. I have also seen similar tiles in another shop they called the red tile Rosa Alicante. The business where I have placed the order (I have purchased from them in the past) call the tiles Rosa Travertine and Cream Travertine. Could you please give me your views on the names they have given each tile, and if they are all names for the same tiles, they all look very similar. I would describe the tile as a mixture of different shades of terracotta in colour with circular patterns (like stones compressed against each other) one tile had white markings). Barry, Feb 6. ReplyR2: Dear Barry: Rosso Verona is an Italian compact limestone (traded as marble). Rojo Alicante is a Spanish compact limestone (again, traded as marble. All compact limestone are). There are visual differences between the two stones, the most noticeable of which is the fact that Rojo Alicante shows some white veining, while the Italian stone does not. Travertine is travertine, period. Which means that is not a marble, and it's not a limestone. From a physical and chemical point of view it is very similar to compact limestone (plus the holes!). What makes it different from marble is that it's not a metamorphic limestone. What makes it different from compact limestone is the way it was formed. Ciao and good luck,
Maurizio, USA Reply
R1: No. The names are not the same. You want Rosso Verona not Rojo Alicante. As for the cream color it sounds like the botticino could be Botticino Semi Classico. Regards, Steven. USA Reply
A 1395: I am an interior designer from Australia, who has moved to the UK. I am interested in finding contact details for a company I heard of before I left Australia. I'm sure their name or product is called Progrind- it is an in-situ process for installing reconstituted stone. I can't seem to locate them doing web searches- can anyone point me in the right direction. Thanks, Anne, Feb 1. ReplyR3: I have heard of the product Progrind. I think the material is an epoxy based grout which is used in fixing agglomerated stone. We can use a solvent less epoxy and mix it with quartz / sand in 1:6 ratio and use it. The consistency can be changed by varying the quantity of the
filler. This is the nearest to Progrind. Another alternative is a polymer modified ready made grouting powder, which is mixed with water and the slurry used for grouting. This is also equally good. If you require any further details on availability of either of the products, please contact me through this site. Regards Arun, India Reply

A 1377: I stumbled across your website while trying to find pictures of serpentine and serpentinite. I found some material at the Morgantown Mine spoils dump in Morgantown, Pa that has me pretty well stumped. I found some large rocks (10-15 lbs) that had dark green bands running through them indicating there might be something inside. Some had lime green/yellow bands. I brought some home and broke them open with hammer and was surprised at what I found. The best specimen had a large green mass inside. I put that in my rock saw and came away with a chunk of rock that is dark olive green in color with roughly parallel wavy white lines. There are also red spots that make the rock appear to be bleeding. It has a slightly greasy feel to it.
I know that serpentine is found there at the spoils and I have found stuff that matches what I have read about it. So I am stumped. Oh ... I did get another fine slab of what I think is the same material but it is dark gray and looks like marble.
Attached a picture of the green material in case anyone wants to see it. Thanks, Paul, Jan 28. Reply

A 1293: What is the trade definition of "Polished"? 2.What is the difference between "Buffed" and "Polished"? Thank you! Lise, USA, Jan 1, Reply
R2: 1) Polished- The end result in stone is the full range of color is seen in the stone. The surface will have a glossy appearance. The process is friction. Typically diamonds or silica carbide and pressure. 2) Buffed- Brings to mind the process used to apply a sealer like a wax. Applying a coating on top of a surface. The difference between the two is polishing is using friction to achieve a look. Buffing is applying a substance to achieve a look. Best regards, Steven, USA Reply
R1: Dear Lise: The definition of polished can be summarized as follows: A fine grinding action designed to smooth the surface of the stone to the point of producing a deep gloss. I honestly don't know the difference between polished and buffed. I just don't know what the latter means. What I do know is that stone can't be buffed. In fact, nobody buffs, say, a floor. One buffs the wax (or whatever else topical finish) that was applied onto the floor. There's no finish onto stone that one can buff, unless, of course, one applies one. But it takes specialty finishes, and special equipment and skills to do that. What's more, such a procedure is only meant to preserve the gloss of the polished stone, never to make it. I hope I answered your question the way it was meant. Ciao and good luck, Maurizio, USA Reply
A 1294: I'm looking for suggestions on slate for a kitchen floor that will look good with a blue pearl granite countertop.

A 1273 B: I was recently at a display of countertop slabs and I saw some slabs with impressive red, pink, and brown large and small inclusions in a green background, as if it were a metamorphosed sedimentary rock with pebbles and stones embedded.

A 1243: The Kentucky State Capitol Building, built in 1904-1909. They have a red marble which I am to trying to locate the origins of and have looked at every sight I can find. I have not yet found the exact match. Any suggestions? Linda, USA, Dec 6. Reply
R3: Dear Linda, if it is local stone, it is probably limestone of Paleozoic age. Please, send image (s) and then it will be possible to identify the stone. Daniel, Slovakia, ReplyR2: Hello Linda! What do your red marble look like? Is it just red or is it red with cream veins etc...? Atkin, USA Expert Panelist, Reply
R1: Linda, finding that elusive exact match may prove impossible, unless you can access some of the original building specs. Somewhere in the contracts, the source of the marble should be specified. But even then, chances are that the quarry has not produced stone in a very long time. Here in Texas, two very old quarries have been reopened on a very limited bases to provide stone for court house restorations, and I might add, it was a difficult task. Not being familiar with the geology of Kentucky, I can't say that a red marble was ever produced there, but I do know that a red or pink marble is produced in your neighboring state of Tennessee. That might be the source. But then again, the source may be in Europe. Have a good marble and granite fabricator (one who has access to a lot of stone) and get their opinion. Be prepared to send off small samples of the stone if at all possible to get an identification. But most of all, don't give up. Someone will know the stone, and where to get it. Good luck, JVC, USA ReplyA 1232: You helped a subscriber with some expressions of Stone Business. The message encouraged me to consult with you on crucial problem one faces in marketing for Natural Stones. How can we equalize the stone commercial names used in your messages with the stones we have in our warehouses? Words ( names ) like Bianco Gioia, San Mateo Lime Stone, Vizag Blue, Juparanas, and ... so on. We are losing many occasions for not being able to compare these unscientific names with the stones we may have available to meet the inquires.
Would you please help us to find the solution? Nov 30. Reply
R3: One problem is every supplier changes the name to protect his source. That way no one knows where the stone came from. Randy, USA, ReplyR2: You can't. There are too many channels of distribution without any central body assigning names. Amusingly, some products are not even granite. Regretfully, Steven, USA Reply
R1: Your request reflects
a deep concern that is highly commendable. It is also, alas, as rare
as an albino fly! On the other hand, it (your concern) is totally hopeless,
because it's not "politically correct". The current establishment of
the stone industry World-Wide is much against the disclosing of the
different classifications of stones. For the "sake" of the industry,
they want "to keep things simple", so that any idiot with a freshly
printed business card can get involved in the stone business. In other
words, they're trying to condense in a telegram format a whole science,
namely petrography. Even if I did help you with a more scientific classification
of the different stones that you have in your warehouse, my input would
be totally unofficial, therefore toothless, and, therefore again, a
total waste of time. Although based on scientific grounds, it would
only represent my opinion. Is there anything that can be done about
it? I do believe so. How to go about it is a different story, however
I do know that it can't be expected from the recognized industry's authorities,
unless the federal government kicks in a force them to. Long ago I reached
the conclusion that the action must be taken from without the
industry's establishment and, somehow, eventually forced upon them.
At that time I also reached the conclusion that I could not do it by
myself. But then was then, and now is now. If something is ever bound
to happen, we must all thank to site's like this one that represent
the stone industry in real-life terms, through these open forums. Guys
like me, by volunteering their time and expertise, have been having
the opportunity to voice their opinions, by answering to all the gripes
and disappointments of real stone end users, who've been literally victimized
by the offspring of the general "politically correct" ignorance dominating
the industry. Our answers and comments gave us more exposure than the
"politicians" running the show ever hoped for. We're just at the beginning
of a crusade that's way overdue, but I have the funny feeling that
Dear Maurizio: I wanted to congratulate you on your response in reference to the question to Stone Names. I have been involved in the research &development for stone/masonry &fine surface care for 27years.

R2: I only classify two Cream of Marfils. One from Spain & one from Turkey. Visually there is a difference between these 2 products. I have not studied the petrography of the two stones to give you more information. Best regards, Steven, USA Reply
R1: "Crema Marfil" is indeed compact limestone which is quarried in Spain. I comes in voluntary grading (in other words, to the good heart of the quarrier) dubbed "Commercial", "Select", and something else that I don't remember. It doesn't matter much, anyway, because the dealer has no legal obligation what-so-ever to disclose such (unofficial) grading to you. There's no difference between the Spanish, and Italian, and Iranian "Cream Marfil", because there are no other "Cream Marfil" but the one coming from Spain. I don't know about the Iranian one, but if you stumble upon a slab of "Cream Marfil" with the brand "Made in Italy" on it, it only means that some Italian stone processing plant bought blocks of the stone from Spain and processed in Italy.

R3: David, As far as I know there have been three classifications of Blue Pearl that have been offered to importers over the last few years.
