Weight and size of gemstone/item may vary slightly from piece to piece due to difference in calibration of our weighing and measuring scales compared to those used by buyers.

Colour may also not appear exactly as in real life due to variation in computer monitor resolution and lighting used during photo shooting. Our photos are taken under fluorescent lighting; sometimes Torch Light and Flash Light are also used. We will do our very best to represent the accurate pictures of all our items.
