Dioptase Quartz Crystals

Dioptase and quartz form a stunning duo, with dioptase crystals embedded in or on quartz, creating a truly breathtaking sight. This unique formation occurs in specific copper deposits, particularly in oxidized zones where copper minerals have undergone chemical changes.

The crystals are remarkably transparent to translucent, boasting a vitreous luster that showcases their exceptional clarity. Their prismatic shape is defined by sharp, well-defined edges and smooth, flat faces that reflect light like a thousand tiny mirrors, adding to their mesmerizing beauty.

The vibrant blue-green hue within the quartz crystals comes from dioptase, a rare copper silicate mineral. Typically found in association with copper deposits, dioptase's presence in this specimen hints at a complex geological history involving copper mineralization, making this specimen a true treasure for collectors and geology enthusiasts alike.

Micro Dioptase Inclusions

Scattered throughout the quartz crystals are micro dioptase inclusions, tiny flecks of vibrant blue-green color that add a mesmerizing contrast to the crystal's transparent matrix. These inclusions are incredibly small, measuring only a few micrometers in diameter, yet they impart a profound impact on the specimen's overall appearance. The micro dioptase inclusions seem to shimmer and glow from within, as if infused with an inner light that radiates through the crystal.

Key Characteristics

Dioptase Color: Dioptase is known for its vibrant emerald-green to bluish-green color, which adds a pop of color to quartz crystals.

Quartz Properties: Quartz is typically colorless or white, providing a beautiful contrast to the green dioptase crystals.

Formation: Dioptase forms on or within quartz crystals through directional deposition late in the quartz growth cycle.

Notable Localities:

Namibia: The Kaokoveld Plateau and Tsumeb Mine are famous for producing high-quality dioptase-quartz specimens with striking crystal formations.

Congo: Reneville, Congo, is another notable source of dioptase-quartz specimens, often featuring green dioptase crystals on quartz.

Arizona, USA: The Mammoth-Saint Anthony Mine near Mammoth, Arizona, has produced small dioptase crystals on quartz.

Specimen Quality and Rarity

The specimen of prismatic quartz crystals with micro dioptase inclusions is an exceptional example of its kind, showcasing a unique combination of crystal clarity, prismatic shape, and vibrant micro inclusions. The rarity of dioptase and the exceptional quality of the quartz crystals make this specimen a true treasure for mineral collectors and enthusiasts.
