ABOUT THE ITEM
Alexandrite is an extremely rare color-change gem. It is a phenomenal variety of chrysoberyl that changes from greenish in daylight to reddish in lamplight. Alexandrite is sometimes described as "emerald by day, ruby by night".
Crafted in platinum, this custom made necklace is our VERY FIRST signed piece! This platinum necklace features a very rare, untreated natural color-change alexandrite mounted in a four prong basket setting, as well as four bezel set diamond stations. The alexandrite weighs 1.27 carats and changes from bluish green in daylight to grayish purple in incandescent light. The necklace measures 19.25 inches long. Near the lobster clasp, the piece has a tag stamped with our "GLOBAL GEMOLOGY" signature, while the clasp itself is stamped "Pt950".
Accompanied by GIA Alexandrite Origin Report #2225678687.
