The first thing to decide when purchasing a Tiffany Style Diamonds is the shape of the stone. There are nine major shapes of diamonds.
How the wholesale diamonds have been cut, polished and to what proportions and symmetry are important, as these factors determine the life, brilliance and dispersion of the unique engagement ring. If the cutting factors fall below standard the appearance of the unique engagement ring is adversely affected.
Dont be fooled into buying Tiffany Style Diamonds that is said to be .25 points. It is NOT a quarter of a carat, and will be so small that it should only be used as accent to other stone or the gold itself.
