Round 10 Mm 4.5 Ct Vvs Natural White Sapphire Modern Brilliant Diamond Cut Stone:
White Sapphire is the Master of Gemstones. It is second to none but to Diamond and it is the closest to it int hardness, while Diamond hardness is 10 degrees on the MOH scale, Sapphire hardness is 9 degrees. Sapphires are available in many colors but Blue is the majority. The coloring is caused by coloring oxides inside the crystals. Rarely, when there are no coloring oxides present the stones becomes colorless and we have White Sapphires. The good color good clarity good cut White Sapphire looks very much like Diamond. When mounted on a ring for example, only and experienced eye will tell it apart from a Diamond because its sparkle is subtle, not like Zircon and synthetic stones.

IMPORTANT NOTICE: White Sapphires are so rare to the extent that so many jewelers didn't have the chance to see them in their lifetime. Even most Gemologists didn't have this chance. Therefore it can easily be mistaken for Diamonds, White Topaz, even Zircon. These stones have been treated by the HTHP (High temperature high pressure) method which was originally used to treat Diamonds. This treatment expels impurities and gasses from inside the crystals thus dramatically improving its clarity and color. This process is applied to the rough uncut crystal and doesn't affect any of the stones other properties. However, it causes the crystals to fuse internally which would confuse some inexperienced people who would examine them and would lead them to wrong conclusions. Therefore I have to point out that the only and the best way to properly identify White Sapphires is to use the device called Presidium Duo-tester. It tests the thermal and optical characteristics of the Gemstones beyond any doubt.
