| Description |
A very fine miniature of "desert rose" habit Gypsum from the Red River which runs through Winnipeg. This specimen has excellent amber color and great damage free crystal growth. These pieces will fluoresce in a blue color under longwave UV, and the color is more intense in the highly saturated orange/amber varieties such as this piece demonstrates. The piece is also highly phosphorescent after removal of a uv light source.
