A diamond simulant, diamond imitation or imitation diamond is an object or material with gemological characteristics similar to those of a diamond. Simulants are distinct from synthetic diamonds , which are actual diamonds exhibiting the same material properties as natural diamonds.
The Federal Trade Commission (FTC) also ruled that lab-grown diamonds are real in 2018. “Laboratory-grown diamonds and natural diamonds cannot be told apart using the unaided eye,” GIA argues ...
Lab-grown diamonds of various colors grown by the high-pressure-and-temperature technique. A synthetic diamond or laboratory-grown diamond (LGD), also called a lab-grown diamond, [1] laboratory-created, man-made, artisan-created, artificial, synthetic, or cultured diamond, is a diamond that is produced in a controlled technological process (in contrast to naturally formed diamond, which is ...
Diamond reports from GIA (as well as other, for-profit sources) are now demanded by most consumers purchasing diamonds over a certain size, typically for over 0.5 carat (100 mg), and almost always for over 1.0 carat (200 mg), and are considered an important tool in guaranteeing that a diamond is accurately represented to a potential buyer.
We used the diamond tester just to be sure, but in fact it does test as diamond, not as CZ. What you have is a ring that looks like it's eight to 10 carats from the top, and ... it's a diamond.' ...
As a diamond alternative, Moissanite has some optical properties exceeding those of diamond. It is marketed as a lower price alternative to diamond that does not involve the expensive mining practices used for the extraction of natural diamonds. As some of its properties are quite similar to diamond, moissanite may be used as counterfeit diamond.
Diamonds -- fake and real -- are perhaps the best example of this. So 30 years ago, when one London-based woman found a huge, gorgeous and fake diamond ring at a car boot sale (almost the ...
Diamond is extremely strong owing to its crystal structure, known as diamond cubic, in which each carbon atom has four neighbors covalently bonded to it. Bulk cubic boron nitride (c-BN) is nearly as hard as diamond. Diamond reacts with some materials, such as steel, and c-BN wears less when cutting or abrading such material. [4]
