First of all most stones will scratch glass...A cubic zirconia sapphire and ruby and quite a few other stones are harder than glass...A diamond can be broke by just banging it into you car door accidentally and I have seen that happen...Unless you have some pretty special equipment or a lot of knowledge at what you are looking at your not going to ever be certain...Take it to a jeweler and have them look at it or even a pawn shop, usually they have a tester they can touch the stone with and know in a second if its real or not without having to get a real appraisal and they will probably do it for you for free

Yes, a black di<b>a</b>mond is a real diamond. It is just has some other mineral in with it, that is what gives it the black color. The Canary diamonds, a yellow tinged diamond, have a similar property.\nALSO. Kimberlite ore, a substance often found around diamonds, is black. If this a a rock that you actually have, then you may have a piece of kimberlite.

Wow it is scary reading some of these answers... Take it to a reputable jeweler in your town and they will test it using  a touchstone and several different types of nitric acid to test. If this is done wrong you could ruin your piece of jewelry.... fire is certainly not your answer... gold meltsssssssssssss..most jewelers and I mean jewelers can tell just by looking, though sometimes even they need to test a piece...

That depends on many factors. First of all, you would have to weight the rough stone and determine how many carats each was. Then, and most importantly, you have to judge the quality of the stone: intensity and quality of the color, inclusions, origin of the stone, and how much of that rough could be used into cutting the stone. \nIf all three stones were top quality (from top origins, and without treatments, top color, clarity and so on), it could be something like: Emerald, Ruby, Sapphire. \nStill, take into account that this goes by particular specimen (and this applies to many gemstones) and not so much by species. \nRough, uncut stones are hard to judge, since the inclusions are harder to see, and you don't get a good sense of color. \nYou can probably get a good piece of rough stone for not too much money. If you are looking to have it cut or polished, though you may be disappointed, as very little of it may be useful. \nIf you are looking to buy stones to wear, I recommend that you look into cabochon cuts: this cut makes the color look beautiful, whilst using lesser quality (clarity wise) stones, so it's not as expensive, and you may find big, beautiful pieces that are ready to be set. \nHave you considered buying spinels? They come basically in every color, and they are so shiny that they glitter even in their rough, unpolished forms. \nGood luck!

these are really beautiful (Hot Diamonds silver necklaces) and they come in an expensive looking box too.\n\nhttp://www.dotjewellery.com/shop/frameset.asp?gclid=CM2wr8aUlYgCFRZrQwodJC-X_A\n\nThey are a really good company, I've had things from there in the past and hot diamonds is a very nice brand.

I did a quick search on www.bluenile.com-\nThere were no diamonds which met your exact specifications, however the closest was a .24 ct E color ("D" is colorless), Internally Flawless (a grade below flawless), Ideal cut.  It was selling for $786.\nA .26 ct Good cut, D color, Internally Flawless stone was $610.

Diamonds are matched and paired when they are made into earrings, basically, they should be very similar in carat, color, cut and clarity.  They should be mounted with the same styles, thus you are not supposed to tell the difference with your naked eyes.

Synthetic diamond has been used for industrial processes for years and is now a little cheaper than natural material. It is often better than natural as the grain size and shape can be controlled. In recent years a large number of synthetic gem diamonds have been coming onto the market from Russian producers. Finished cut stones are wholesaling for something like $60 - $80 per carat.

There is an equipment use in jewellries store,..to check wether a diamond is genuine or not.If the jewelry is diamond,..this equipment will make a beeping noise/alarm.\n\nIf u can borrow..one of this equipment,..it will be faster.

ebay, just make sure you note that it is REAL diamond jewelry--there's a lot of fake stuff on there, so point out that yours isn't CZ in the description and put "REAL AUTHENTIC DIAMOND" in the headline

actualy it's very easy. most real alexanderite on the market is a brite green (like a good emerald) or a bluegreen which turns either a light red or light redish purple. Most of the time the color change isn't complete. The exceptiion would be the extreamly high end stuff. The color change is always subtle in natural stones.\n\nI've seen lab created stuff, it looks more like mystic topaz than actual alexanderite. i don't have any of the sites memorized but do a search on the stone to get an idea of what i'm talking about.

VERY CAREFULLY UNLESS YOU ARE AN EXPERT IN THE DIAMOND TRADE

They do have the ability, but they will probably confiscate the money if it is found to be fake.  There are cheap devices you can get to check money yourself.  They are called Counterfeit Money Detection Systems and the lower end ones sell for under $20.00.
