Fine Chrysoberyl var. Alexandrite

Sri Lanka
Named for Tsar Alexander II, this rare and beautiful gem, of top quality, is hardly used in modern jewelry due to its rarity. In antique Russian jewelry you may come across it with a little luck, since Russian master jewelers loved this stone. Tiffany's master gemologist George Frederick Kunz (1856-1932), was also fascinated by alexandrite, and the jeweler's firm produced some beautiful rings and platinum ensembles at the turn of the last century. Smaller alexandrites were occasionally also used in Victorian jewelry from England.

The present offering is a cushion-shaped chrysoberyl var. alexandrite changing from green to pinkish-brown, with changes in color observed in fluorescent vs. incandescent light. Weighing approximately 3.84 carats and measuring 12.53 x 8.29 x 4.30mm

Footnotes

Its color changes from green to pink-brown showing a strong degree of color-change of 70 - 80% and very good quality of color-change.
