Comment: Though certified as "colorless" I keep on seeing a hint of pink in this giant Danburite. The razor-sharp Wieland cut and the checkerboard make for a dazzling light play. Some colorless inclusions are visible only under the lens but there make a fascinating detail to study. 14mm square, a truly big gem not for a ring under size 8, but better still for an impressive pendant. Danburite is a relatively new gemstone with good brilliancy and durability. If you currently don't want to shell out $4m for a 15+ carat diamond this is a good alternative.
