As posted in the section CSI: Colored Stone Identification:
Quote:
A gem can not be identified by looking at a picture. If all you can provide is a photo of an unknown gem, please do not post it.
Identification requires additional information, like refractive index, specific gravity, microscopic observations, physical characteristics like fracture/cleavage descriptions, etc.
If it is impossible for you to obtain any of this information, you are advised to bring your unknown to a professional who can decide which tests are necessary for identification.
We are happy to provide recommendations to help you find a professional.
And, now a word for established members: A request for help in identification is NOT a game. You DO NOT have to make a guess about what you think the specimen is.
If you are going to post an answer, please give a full explanation as to why you have come to that conclusion and decided to post it as a possibility. Thanks.
I apologize. This is my first time on here. I don't know how to get any of that information. I just found this and thought maybe a could get some suggestions about what these stones are.

Are the backs (behind the gems) open or closed? Could be nephrite, a quartz variety (natural or dyed) , glass or plastic.
Have you done a touch test? Put one of the stones on your upper lip. Does it feel room temperature or cold?
Also, contact your closest Gem & Mineral Society. Ask to attend their next meeting and ask for some help. It's a lot easier to identify something if it is in front of you. http://www.rockhounds.com/rockshop/clublist.shtml
