Alexandrites are among the rarest treasures in the gem world, and one of the finest examples on the market today takes center stage in this exquisite ring. Weighing approximately 5.50 carats, this captivating, round brilliant-cut gem is set in 18K white gold and accented by .71 carats of colorless diamonds the encircle it and flow down the shank. Certified by C. Dunaigre Switzerland, this exceptional gem exhibits the unique green-to-violet color change for which these stones are renowned. This color change depends on the stones reaction to natural and incandescent light. It displays an emerald green in daylight, and a beautiful purple in incandescent light. 

While the alexandrites almost magical trait of dramatically changing colors in varying light makes it extremely valuable, its history makes it all the more intriguing. The first Alexandrite was discovered in Russia in 1834 on the birthday of Czar Alexander II. The czar claimed all subsequent finds of this natural chrysoberyl for the throne, making this truly the gemstone of royalty.
