A remarkable gem that is as beautiful in-hand as it is fascinating. In standard lighting, the gem is a light pink and, with Calcite’s optical properties it is very dispersive and dazzling. Entirely clean and very large, the cutting and polish have been done by an AGTA award winner and it shows - simply fantastic. Now for the fun part; under longwave UV the gem is a light to medium yellow, a wild contrast to its bodycolor. Then, with shortwave UV the gem takes on an intense blue-white color that is actually a phosphoresence - that is, it continues to glow this color for 5-10 seconds after the light source is removed. A dramatic effect indeed. A gem treasure!
