Low; high-volume mineral or byproduct
Similar Diamonds
None; this is not a diamond specimen
Setting Suggestions
Wire wrap or bezel setting for specimen display
Care & Maintenance
Keep away from harsh chemicals and high heat; clean with soft brush
Interesting Facts
The intense blue color and conchoidal fracture suggests a silicate or copper-based mineral rather than carbon.
