Danburite is a transparent to translucent gem and ranges from colorless, to light yellow, or pale pink to light brown in color. It has a hardness of 7-7.5 on the Mohs scale with a fairly high refractive index, surpassing quartz and rivaling topaz in brilliance. Danburite was first discovered in 1839 in Danbury, Connecticut by Charles Upham Shepherd, a renowned American mineralogist. The original deposit is now buried under the city of Danbury. However, it is also found in Russell, NY; Charcas, San Luis Potosi, Mexico; Kyushu Island, Japan; Mogok, Burma; Uri, Switzerland, and Madagascar. Most of the danburite in today’s commercial market is from Mexico. This 32ct fancy oval cut gem exhibits a very pale brown color, almost colorless. It is the largest danburite from Burma in the National Gem Collection.
