Dioptase Appraisal

Dioptase Crystal Cluster

This item is a crystalline mineral specimen, likely a cluster of natural dioptase crystals, given its distinctive vibrant emerald green color. The specimen is composed of numerous small, well-formed individual crystals, most of which exhibit a rhombohedral or tabular habit, typical of dioptase. These crystals are densely packed, forming an aggregate or druse on what appears to be a very minimal or non-existent matrix. The size of the overall cluster is not precisely discernible from the image, but the individual crystals appear to range from approximately 1 to 5 millimeters in their largest dimension. The color is a rich, saturated dark green, showing some variation in shade, suggesting depth and natural light interaction within the crystal facets. There are a few small, lighter, possibly white or very pale yellow inclusions or attached mineral specks visible on the surface, which could be part of the host rock or another mineral growth. The crystals display a vitreous to sub-adamantine luster, indicating good crystal formation and a clean surface. No significant damage such as chips, cracks, or repairs are clearly visible, and the specimen appears to be in excellent condition with its natural crystal faces intact, suggesting careful extraction or natural formation without significant environmental weathering. The craftsmanship is entirely natural, showcasing the geological processes that form such crystal aggregates. The estimated age is geological, as it is a natural mineral formation.
