Crystal Specimen Appraisal

Iridescent Carborundum Crystal Specimen (Silicon Carbide)

The item is a raw, jagged specimen of what appears to be iridescent Carborundum (Silicon Carbide, SiC). Its physical characteristics include a predominantly dark, almost black base color, heavily interspersed with brilliant, sparkling iridescent flakes that reflect light in a spectrum of colors including blues, purples, greens, yellows, and oranges. The surface is highly textured and rough, indicating a crystalline structure that has formed in layers or aggregates, giving it a somewhat flaky or lamellar appearance in places. The overall shape is irregular, characteristic of a naturally occurring or synthetically grown crystal cluster that has not been polished or cut. Size cannot be definitively determined without a scale, but it appears to be a hand-sized specimen. There are numerous sharp edges and points throughout the piece. No discernible manufacturing marks or signatures are visible. The iridescent effect is a notable feature, often referred to as 'peacock ore' due to its vibrant color play. Its condition appears to be stable, with the inherent ruggedness being part of its natural or synthetic formation rather than damage. There are no obvious signs of wear, repairs, or significant breakage beyond the natural cleavages and fractures of its formation. This material is known for its extreme hardness and abrasive properties. Given its appearance, it is likely a modern synthetic crystal, commonly produced for industrial applications but also valued as a mineral specimen for its aesthetic appeal. The craftsmanship is inherent in the crystal growth process, presenting a naturalistic and intricate structure.
