These natural alexandrites weigh 0.37 Carats total weight and are cut into ovals that measure 4.0 x 3.10 x 2.22mm, they are clean even under a loupe. The color change on these are outstanding going from Blue-Green changing to Purple without any grey modifiers. These would make a great pair of earrings or side stones for a ring as they are extremely durable. I have 2 pairs of pear shape alexandrites around this size that match in color and quality so please contact me if they are of interest. A very rare find!
