Thumbnail (2.16 carat). Dioptase gems in sizes above 1 carat are very hard to obtain. Although not totally clean, this is overall mostly transparent, and has an even and saturated color. A beautiful rare gem. A well-cut, rare gem - notable in size - cut by Spectrum Award winner Mark Kaufman. Ex. Charlie Key.
