Natural Dioptase Specimen – 20g, Muldiva QLD

One of the most intensely coloured minerals in the world — this natural dioptase specimen weighs 20 grams and originates from Muldiva in Queensland, Australia, a locality that has produced some genuinely fine examples of this rare and spectacular copper cyclosilicate mineral. Dioptase is celebrated among collectors for its extraordinary emerald to deep blue-green colour, which rivals even the finest emeralds in saturation and intensity, and its well-formed, transparent to translucent rhombohedral crystals that catch the light with a vitreous lustre.

Dioptase forms in the oxidised zones of copper ore deposits, typically in arid environments, and Australian specimens carry the added appeal of strong local provenance from a country not widely known for this mineral species. Muldiva material is particularly sought after by collectors who appreciate both the quality of the crystals and the rarity of the locality.
