Weight: 275g / 9.7oz
Dimensions: 4.2 × 3 × 1.3 in
An eye-catching cluster of deep emerald-green dioptase crystals richly covering a brown limonite matrix. The dioptase displays sharp rhombohedral faces, intense color saturation, and a sparkling druzy surface across much of the specimen.
This piece comes from the famed Tantara Mine in the Democratic Republic of the Congo, known for producing some of the finest dioptase in the world. The contrast between the green dioptase and the earthy matrix is stunning. Suitable for both display and advanced collections.
