Dioptase on Matrix · Thumbnail Specimen

Dark emerald-green Dioptase crystals rise from a contrasting cream, ochre and pinkish-brown matrix. The crystal group has an irregular, open outline, with several substantial blocky crystals standing above the host material. Exposed matrix separates parts of the green growth and helps define the individual crystal shapes.

The larger crystals have broad reflective faces, with brighter green areas visible near thinner edges and smaller growth. Their glassy lustre contrasts with the rough, granular texture of the matrix. Some faces appear smooth in reflection, while others show fine steps and uneven surface detail.

The side views reveal a more three-dimensional arrangement than the main face initially suggests. Crystals project at different angles from the supporting material, and smaller green crystals occupy spaces between the larger forms. This makes the boundaries between matrix and crystallisation an especially useful part of the specimen to examine.

The pale associated material has not been conclusively identified. Fornacite has been suggested in the supplied mineral details, but the association remains unconfirmed and is not presented as a definite identification. Its visible contribution can still be described: an earthy, finely textured surface that contrasts with the bold green Dioptase crystals.

The photographs record the exact specimen from four angles, showing both the principal crystal group and the exposed host material. Together they allow the crystal outlines, surface lustre and distribution of matrix to be compared without treating every pale area as the same identified mineral.
