Not a diamond; this is a faceted quartz crystal or potentially glass containing pronounced internal stress fractures, feather inclusions, and distinctive rainbow iridescence from thin-film interference or micro-fractures.
Not a diamond; this is a faceted quartz crystal or potentially glass containing pronounced internal stress fractures, feather inclusions, and distinctive rainbow iridescence from thin-film interference or micro-fractures. · Custom carved or heavily faceted geometric block / modified cube shape.
Fair to Poor (non-standard optical proportions, designed purely as a decorative mineral specimen rather than a precision gemstone). Cut
Carat
Significantly oversized for standard gemstones (weighs more like a mineral specimen or paperweight, potentially several hundred carats equivalent).
Color
Colorless base with vivid rainbow interference colors (aurora/mystic coating effect or natural fracture iridescence).
Clarity
I3 (Included heavily with massive internal fractures, feathers, and stress planes).
Shape
Custom carved or heavily faceted geometric block / modified cube shape.
Overall Assessment
This item is an interesting, large mineral specimen (likely quartz or glass) featuring striking internal fractures and rainbow light dispersion, but it holds no gemological or monetary value as a diamond.
Cut Quality
Fair to Poor (non-standard optical proportions, designed purely as a decorative mineral specimen rather than a precision gemstone).
Brilliance
Low to Moderate; obstructed heavily by internal fracture planes and stress lines.
Fire
High chromatic dispersion visible specifically along internal fracture planes due to thin-film light splitting.
Scintillation
Fragmented and erratic sparkle pattern caused by internal light leakage and fracture scattering.
Proportions
Non-standard; deep blocky geometry with wide table-like top and complex internal reflection planes.
Symmetry
Fair (irregular geometric facets showing noticeable asymmetry).
Polish
Good on outer flat facets, but internal fracture planes remain unpolished.
Fluorescence
Cannot be reliably determined without UV testing, though interference effects dominate visible light.
Inclusions
Pronounced curved and linear internal feather fractures, stress cracks, and localized mineral inclusions creating optical disturbances.
Blemishes
Surface scratches, impact marks, and abrasion along the edges.
Origin
Natural quartz or synthetic crystal matrix, possibly treated with a surface metallic vapor deposition (aura coating).
Treatment Detection
High probability of surface coating (such as titanium or gold vapor deposition for the rainbow effect) and natural or induced thermal shock fractures.
Estimated Value
Nominal decorative value as a mineral specimen (roughly $20 - $100 depending on size and origin).
Certification Estimate
Not eligible for standard diamond grading laboratories (GIA/AGS); would be classified by mineralogical institutions as a crystal specimen.
Investment Potential
None; purely decorative specimen value.
Similar Diamonds
None, as this is fundamentally quartz or glass rather than diamond.
Setting Suggestions
Not suitable for jewelry wear; best displayed as a standalone decorative crystal paperweight or mineral cabinet specimen.
Care & Maintenance
Handle with care to avoid worsening internal fractures; clean gently with mild soap and water; avoid harsh chemical ultrasonic cleaners.
Interesting Facts
The vibrant rainbow colors visible inside are typically caused by light diffraction passing through microscopic gaps in internal cleavage or fracture planes, artificially enhanced in some stones via vapor deposition (Mystic Quartz).
