[9/2 10:00 PM Sale] Brazilian Alexandrite 2.8mm/0.112ct Loose Gemstone with Identification Report
Alexandrite is often called the "king of gemstones." It is a mysterious stone known as the "emerald by day, ruby by night" due to its color-change properties from green to red. This particular specimen is a Brazilian alexandrite. Please enjoy the color change using a red-light penlight.
This is an alexandrite from the Hematita mine in Brazil. Purchased directly from the mine owner, it features high transparency and a clear, distinct color change depending on the light source. It shifts from bluish-green under natural light to reddish-purple under warm lighting. It is a round cut, measuring approximately 2.9mm. Though small, it is a loose stone that fully captures the characteristic color-changing charm of alexandrite. An identification report is included.
