and I'm trying to find out how to identify a stone my mother-in-law dug up in Oaklahoma some forty-odd years ago. Looks to me like a piece of glass but doesn't at the same time. Searching the web, the closest I can come to it is some type of garnet. It's a light blue- green and about the size of a cantaloupe. I say its glass...my wife says no. BTW, it was found in the same general area as fist-size piece of flint. Any Ideas? Thanks

Welcome beedees,
With flint stones being found lying around you may have a large diamond on your hands? Have you did a hardness test or anything? Simply take a piece of window glass-----a broken piece will do, take the edge of the stone and see if it will scratch the surface of the glass. If it does you may have a very large diamond?
I would definitely have it checked out. Good luck to you and I do hope it is a diamond in the rough? Could be worth millions of dollars?

O.K., it scratches glass......now what? It shows several large internal fractures, if it was glass, wouldn't it seperate easily?

I don't know if I am replying to beedees or not? But yes if it scratches glass it is not glass. Most likely it is diamond. Diamond is the toughest known mineral and I believe it is the only one that scratches glass.
You should go to a local jeweler that you can trust. If this is a real diamond and is the size of a cantalope then you are talking millions of dollars. Be careful.

Jeweler saya an interesting piece of glass, no bubbles he could see and under black-light should be white if glass, but had no color. Sorry about the name confusion but can't seem to reply using beedees.

I would not trust that jeweler. Buy you a jeweler's lense to look for diamonds. Under a light will only show infractions. If the stone scratches glass most likely it is diamond. I do not think glass will scratch glass? A jeweler's lense is what you need. Go to a jeweler with a ring and tell him you want to look at the diamonds on the ring-------then pull the stone out and look at it. I believe you have a diamond. I have never heard of a stone of glass?
The reason you can not post may be due to not getting your password correct. Send it in again use maybe another call name and then use the password you make up. You can also retrieve the password you already had. It should be in your email. Best of luck to you.

Thanks for your encouragement, but I still think its glass. Many things will scratch glass I have found, even a piece of tool steel. As for getting a lense, I wouldn't know what I was looking for anyway. Might be best if I forgot about it,LOL. At any rate, it took more effort than I expected to cut the glass ( beer bottle BTW) Is there a different type of glass that woujd be a better test? I found a sharp edge on the rock and pushed with moderate force. From the way it cut, I believe I could ( given enough time and band-aids) cut the bottle in two with it.

I definitely would not give up on it until I could confirm whether it is a diamond or not. The "Punch Diamond" was found in West Virginia during a horseshoe game. I forgot how many carats but something like 25 to 35. You can google diamonds to see what some of the larger ones look like and see if there is any simularities. You must remember these stones have to be cut to make them look the way they do. You have heard of "diamond in the rough?" I believe that is what you have-----if so they could cut at least 15 to 20 large stones from yours and each would be worth about 1 to 5 million dollars. Please take a little time and have it checked out further. After forty years I would not lay it up for another year until I found out one way or the other.
You can also do a hardness test on the stone. Take a small portion of it and it to see if it shatters. Glass will turn into dust while diamond will not. But I believe your best bet is a local jeweler with a jeweler's glass. It will readily confirm one way or the other. Hang in there and please have it checked out.

Sorry, you lost me there. Take a small portion of it and do what to it? Hitting diamond with a hammer reduces it to a powder.

I didn't say to take a hammer to it. There are ways to check out the stone to see if it is a diamond or not. You can check for hardness, weight and specific gravity. But, the easiest way is to use a jeweler's lens. Surely you can find someone that has one? Even the local pawn shops has a jeweler's lens. But, if you really have a diamond that size you need to be very careful and take it to someone trustworthy.

Not a chance it's a diamond, but the guys best guess is it's some sort of optical glass, there being NO bubbles in it he could see.

I personally would not take some guy's best guess? I would take it to a reputable jeweler, have it checked out. A guy's best guess will maybe cause you to lose millions. Tomorrow he will ask you to sell it real cheap, the next thing you hear is someone found a large diamond worth $50 Million Dollars. I don't think you would like that very well. Have it authenicated and then you can throw it away or you may be rich? I sure wouldn't go by some guy's best guess? Good luck.

BEEDEES,
you might consider that since it was found in oklahoma,that near nashville arkansas is the crater of diamonds park where a lot of people have found gem stones,but from the color you disrcibed i would call it a saturnine or maybe an aqua marine which is in the corundrum class stones and will cut glass.these stones are also found where saphire ,emerald ,and ruby garnets are found.. with all that being said there is plenty of info on the net to aid you in determining what kind of stone you..the last thing i would depend upon to determine a diamond is whether it cut glass or not. I doubt very seriosly if it is a diamond because look for carbon pots or a six sided crystal shape..but the stone you have discribed is most likely atype of calchite quartz.these rocks when polished are pretty to look at but have very little intrinsic value...

Looked at some calcite on the web and they are different . My Frankenstone shows no crystal structure........ gotta be a piece of glass.
