[Item 12564512] Russian Alexandrite Loose Stone 0.150ct
Alexandrite is often called the "King of Gemstones." It is a mysterious gem whose color change from green to red has earned it the nickname "emerald by day, ruby by night." This particular stone is a rare specimen from Russia. Please use a red-light penlight to enjoy its color-changing properties.
This stone was purchased directly from the owner of a Russian alexandrite mine abroad. You can clearly enjoy the distinctive color change of alexandrite as it transforms its appearance depending on the light source. It comes with a GIA identification report.
