Is Your Gemstone Genuine?
Jewelry is big business and the real value of any jewelry is dependent on the gemstone that is part of it. With this in mind, how do buyers know or make sure that they are paying for the real thing? What are the qualities or characteristics to check or watch for to be sure that the gemstone is genuine?
It takes training and the right equipment to determine if a gemstone is genuine. The term “genuine” means that the gemstone doesn’t only look as expected, it should also meet the physical and chemical characteristics unique to that gemstone. It takes training and the right equipment to determine if a gemstone is genuine or not and there are testing laboratories to do this job.
Before going any further, are treated gemstones still genuine? A treated gemstone, as long as its molecular structure isn’t altered, can still be the real thing but it is no longer natural. Some gemstones are treated to enhance their appearance and decorative value.
What to Check
Yes, there are professionals to perform the tests that determine if a gemstone is genuine or not but it is a valuable asset to any gemstone buyer to know the attributes to be tested.
The following are the characteristics to check:
1. Chemical composition and atomic structure
The atomic structure is what differentiates diamond from other carbon based matter like graphite. The stone’s hardness, and light reflection is dependent on the atomic structure. Gemstones usually have crystalline structures.
2. Hardness and durability
Hardness is reported in a scale of 1 to 10, a method developed by Friedrich Mohs, a German mineralogist. The hardest are diamonds at (10) and the softest is talc at (1). A gemstone should have a hardness of no less than 7.
3. Other physical properties like the refractive index, dispersion and specific gravity.
Testing Laboratories
The following organizations provide certifications on the results of testing conducted. They also provide training and research services to their members.
Gemological Institute of America (GIA)
American Gemological Society (AGS)
American Gem Trade Laboratory of the American Gem Trade Association (AGTA). AGTA the largest trade organization of gemstone traders
American Gemological Laboratories (AGL)
European Gemological Laboratory
The true value of any gemstone shouldn’t be determined by just the physical appearance. Advancements in science have produced synthetic “gemstones” which cost just a fraction of the genuine gemstones. Knowledge is the best protection against paying for the price of the genuine item and getting a “fake”.

hi there fabulous little web-site you got right here
I employ the identical web theme on my own however for whatever reason it would seem to reload swifter on this web site despite the fact that this site has got a whole lot more content. Are you working with any plugins or widgets that quicken it up? If you might be able to give the programs so that I can use them in my webpage so twilight eclipse users could watch twilight new moon online trailers and videos a lot quicker I’d be thankful – thank you ahead of time
