Bornite with Bournonite on Quartz – Metallic Sculpture on Sparkling Crystals
Locality: Dzhezkazgan, Kazakhstan
Dimensions: 5.6 × 3.2 × 2 cm
Dark metallic lustre rises above a finely sparkling carpet of quartz in this distinctive miniature. A prominent bornite cluster stands clear of the broad matrix, creating a striking sculptural focal point. Anthracite-grey to bronze-brown surfaces reveal subtle steel-blue highlights in places, changing with the lighting and viewing angle.
The interplay of textures invites closer inspection. Finely textured, partly rounded surfaces alternate with more sharply defined faces that catch the light with bright metallic flashes. Bournonite adds further mineralogical interest to the bornite-and-quartz composition. Colourless to slightly grey quartz points sparkle between the dark ore minerals, providing a delicate contrast to their metallic presence. The low matrix and elevated principal cluster create a balanced and memorable silhouette.
Bornite, Cu₅FeS₄, is a copper–iron sulphide commonly encountered in massive form, making specimens with distinct crystals particularly appealing to collectors. Bournonite, PbCuSbS₃, is a lead–copper–antimony sulphosalt recorded as a rare associate at Dzhezkazgan. Their combination with sparkling quartz gives this miniature both visual appeal and mineralogical interest.
The Central Asian copper district of Dzhezkazgan is a major sediment-hosted copper occurrence. Its predominantly sandstone-hosted ore bodies have yielded remarkable crystallised specimens alongside economically important copper ores. This piece captures the appeal of those ore minerals in a compact composition, combining intricate surface detail with a strong sculptural presence.
A distinctive collector’s miniature uniting metallic elegance with the delicate brilliance of countless quartz crystals.
In crystal healing traditions, bornite is associated with joy, optimism and embracing change, while clear quartz represents clarity and focus.
