About this specimen
Bottle-green in shadow, hot emerald the instant light finds a way inside — that shift separates dioptase from every other green mineral, and this Congo plate carries it across an unbroken crust. Short blocky prisms and sharp rhombohedral terminations crowd the upper two thirds, thinning to a fine sparkling druse where they meet the host. Below and to the right the ochre limonite breaks through in bare, cavernous patches that make the green read harder still.
Dioptase is a copper cyclosilicate, CuSiO3·H2O, and its colour is the copper itself rather than a trace impurity — which is why the tone holds right through each crystal. At Mohs 5 with perfect rhombohedral cleavage it chips more easily than collectors expect, so lift it by the limonite and keep it away from ultrasonic cleaners and direct heat.
The plate runs 10.7 × 7.6 × 3.3 cm at 275 g, one-hand size, sitting flat on its limonite back without a stand. Every image on this listing is of this piece and no other.
