Bessie G Gold & Telluride Quartz Specimen 6.35 oz For Sale

Bessie G Gold & Telluride Quartz Specimen 6.35 oz La Plata Colorado

An exceptional specimen for the collector who enjoys looking beyond the surface! This 6.35 oz quartz cap from the Bessie G Mine in Colorado’s La Plata Mountains was separated from the vein’s contact zone and displays contrasting metallic mineralization among its quartz crystals.

Under magnification, the specimen becomes a miniature mineral landscape: dark reflective crystals, silver-gray metallic aggregates, bright gold-colored patches, and intricate mineral boundaries tucked between quartz faces. A geologist’s dream to explore under a microscope, with numerous pockets and textures to examine.

What makes this piece special

• Uncommon telluride-bearing locality: Bessie G is known for its gold and silver telluride mineralization.

• Apparent mixed telluride assemblage: Contrasting metallic habits suggest multiple phases, offering considerably more mineralogical interest than a single isolated crystal.

• Visible gold associated with dark metallic minerals: Some yellow material appears along crystal edges and surfaces, making the specimen especially interesting for studying possible alteration and replacement textures.

• Crystalline quartz cap: The quartz provides an attractive setting for examining the metallic minerals and their tellurides include sylvanite, calaverite, krennerite, hessite, and coloradoite. These are possible identifications based on appearance and locality association; the individual species and number of tellurides in this particular specimen have not been laboratory confirmed. The gold’s proposed supergene origin is an interpretation.

  The collecting appeal lies in the combination of provenance, quartz crystal development, apparent mineral diversity, and gold-bearing textures—not simply its metal content. An engaging addition to a Colorado mineral collection, telluride collection, or microscopy study collection.
