Artificial simulants Nowadays the simulants of the diamonds are carried in large masses to cater the needs of the diamond simulant industry. It's that white stuff that you can put over ice cream or perhaps fashion into a fluffernutter sandwich -- if you're into that kind of thing. Instead of using auctions stick with a reputable online jewelry store.
Explanation of Cut, Color and Clarity of This Diamond
Cut Quality Diamonds cut to ideal proportions are made to reflect the most amount of light. High percentage of diamond weight is lost in the process of shaping and polishing the diamond. Such diamonds are perceived as most brilliant and fiery, thus making this the most desirable cut. Because in making ideally cut diamonds more diamond material is sacrificed for the sake of appearance, they are usually more expansive.
Color In the near colorless category H color grade is the second best. Most H color diamonds have a very light yellow or gray tint that may be more noticeable when the diamond is placed on a white surface. Diamonds with H color grade appear white and are great values because they are more plentiful and as a result less expensive.
Clarity Inclusions and external blemishes in diamonds of SI1 clarity may be easy to spot under 10X power magnification. Location of the inclusions greatly affect their visibility to the naked eye. SI1 diamonds of good color produce as good of a sparkle as the more expansive VS graded stones of lower color. Excellent bargains may be fond in this category.
