Jewelry M.S. Rau | Untreated Brazilian Alexandrite Ring, 3.34 Carats

Totaling An Impressive 3.34 Carats, This Rare And Beautiful Brazilian Alexandrite Showcases The Color Change Phenomena. Unlike Their Russian Counterparts That Change From Green To Red, Alexandrites That Hail From The Mines Of Brazil Display A Stunning Bluish-Green Hue Under White Light And Change To A Rich, Deep Purple When Viewed Under Incandescent Light. This Step-Cut Example Is Certified By Gübelin As Being An Unheated Alexandrite Of Brazilian Origin, With No Indications Of Treatment To Enhance Its Phenomena. It Is Beautifully Set In Platinum With Two Accent Diamonds Totaling Approximately 1.00 Carat.

While The Alexandrite Was First Discovered In The Ural Mountains Of Russia In The 1800S, Many Of The Finest Examples Of These Stones Have Been Found In Brazil. For Example, The 17.08-Carat Stone Known As The Whitney Alexandrite Can Be Found In The Smithsonian Museum Of Natural History, Having Been Gifted To The National Gem Collection By Carolyn Wright Whitney. Like The Present Stone, The Whitney Alexandrite Changes From Bluish-Green In Daylight And Fluorescent Light To An Intense Purple In Incandescent Light. In Terms Of Both Rarity And Originality, These Brazilian Alexandrites Are In A Class All Their Own.
