Imitation diamonds are created in a lab by technicians at a reasonably low cost and, therefore, cannot possibly be used as a currency for human misery. Russian linen made items (and Russian linen is still best in the world) was used for special purposes, and still used for wedding, for baptizing child. You might have seen those swimsuits advertised by the great fashion magazines.
Explanation of Cut, Color and Clarity of This Diamond
Cut Quality Good cut diamonds reflects most light that enters the diamond, but not as must as a premium cuts. They are less expensive than the premium-cut. Roughly 25% of diamonds are good-cut based on cut quality. This grade represents an excellent balance between quality and price.
Color Slight presence of color may be detected in F color graded diamonds by an expert gemologist. The diamonds of this grade are considered colorless. Great choice for the purist. Look for a fluorescence rating of faint, inert, none, or negligible.
Clarity The stones of SI2 clarity have inclusions which are fairly easy to see under a loupe with 10X power magnification. Such inclusions may be visible to an unaided eye depending on their location. SI2 clarity diamonds of G or H color look nearly perfect when mounted. For those looking for near perfection these sure come close.
