Garnet (GN):-

Garnets are nesosilicates. 0rigin of name: from ancient Greeks as color reminded them of the pomegranate seed or granatum. Garnets do not show cleavage (the tendency of crystalline materials to split along definite planes, creating smooth surfaces) so when they fracture under stress, sharp irregular pieces are formed. Because the chemical composition of garnet varies, the atomic bonds in some species are stronger than in others. The harder species are often used for abrasive purposes. It is found in the regions of Kenya, Sri Lanka, Thailand, Brazil, India, Madagascar, Canada, USA, Czech Republic and Spain.

American Diamond:-

American Diamond or AD is a synthetic variant of the mineral baddeleyite which is extremely rare in nature. It is the oxide of the metallic element zirconium, zirconium dioxide. It was first used in the Russian space program to serve as a window to photograph through, it was not used in jewelry until 1969 when somebody decided to facet the material. It is often used as a diamond simulant. Cubic zirconia should not be confused with zircon, which is a rare naturally occurring gemstone. Color: By adding other minerals in the creative process AD’s can come in any color as well as the colorless variety.
Hardness: 8.25-8.75
N.B. Key features that distinguish AD from diamond:
American Diamonds have more dispersion than diamonds so show more fire.
An AD has a Mohs rating of 8.5-9 and Diamonds have a rating of 10.
An AD is 1.7 times heavier than a diamond of equivalent size.
AD’s are optically flawless whereas the majority of diamonds have inclusions or flaws
AD has a refractive index of 2.176, compared to a diamond’s 2.417.
AD can be made in most cases entirely colorless: equivalent to a perfect “D” on diamond’s color grading scale but it is rare to find diamonds are truly colorless.
AD’s are thermal insulators whilst diamonds are among the most efficient thermal conductors.
