Description

Exceptional rare micromount featuring well-formed ottensite globules, displaying a striking orange-red coloration with a resinous to sub-vitreous lustre. The ottensite occurs as compact, finely crystallized spherical aggregates, sharply contrasting against slender prismatic stibnite crystals with a steel-grey metallic sheen.

This specimen combines strong visual impact with high mineralogical interest, as quality ottensite micromounts are extremely uncommon, particularly specimens showing such vivid colour, clean development and clear exposure. Crystal preservation is excellent, allowing detailed observation of textures and morphology under high magnification.

Originating from a recent discovery in the Qinglong mining district, a world-class locality for rare antimony minerals, this piece is intended for advanced collectors and specialists seeking uncommon species and refined micromount associations.
