None (Rough/Uncut)
Brilliance
None (Opaque)
Fire
None (Opaque)
Scintillation
None (Opaque)
Proportions
Not applicable to rough material
Symmetry
Poor / Natural Irregularity
Polish
Unpolished / Matte Natural Surface
Fluorescence
Likely orange or pink under UV if Sodalite
Inclusions
Massive white mineral veining (likely Calcite)
Blemishes
Fracture planes and surface abrasions inherent to rough specimens
Origin
Geological sources such as Brazil, Namibia, or Canada
Treatment Detection
None apparent; appears to be a natural raw specimen
Estimated Value
$1.00 - $5.00 USD for a specimen of this size
Certification Estimate
Gemological lab (e.g., GIA) would identify as Sodalite, not diamond.
Investment Potential
None; common mineral specimen.
Similar Diamonds
None; differs entirely from blue diamonds in transparency and luster.
Setting Suggestions
Wire wrapping for a pendant or inclusion in a mineral collection
Care & Maintenance
Avoid harsh chemicals; Sodalite is relatively soft (5.5-6 on Mohs scale).
Interesting Facts
Sodalite is often confused with Lapis Lazuli but lacks the gold pyrite flecks.
