White gold : White gold is an alloy of pure gold with copper, Zinc, Palladium or nickel.
Brilliant cut : The modern brilliant cut was developed by Marcel Tolkowsky in 1919. It consists of 58 facets (or 57 if the culet is excluded). It is the most popular modern cut because it provides maximized light return through the top of the diamond.
Carat : The carat (ct) is a unit of mass equal to 2 g. Carat is used for measuring the weight of gemstones.
Cultured pearls : Cultured pearls are the response of a pearl oyster to a man made tissue implant. This technique is used in Japan (Akoya pearls), in Australia, in Tahiti and China (fresh water pearl oysters).
