Not a diamond; this is a rough green mineral matrix, likely containing olivine, serpentine, or peridot, commonly found in a metamorphic or ultramafic host rock.
Not a diamond; this is a rough green mineral matrix, likely containing olivine, serpentine, or peridot, commonly found in a metamorphic or ultramafic host rock. · Rough crystal matrix, uncut and unshaped.
Not applicable (Rough / Uncut specimen). Cut
Carat
Not applicable to uncut rough matrix material.
Color
Deep olive green with mottled earthy brown and grey host rock.
Clarity
Included / Opaque due to the massive, rough nature of the host rock.
Shape
Rough crystal matrix, uncut and unshaped.
Overall Assessment
The specimen shown is not a diamond, but rather a rough mineral matrix containing green crystalline material, likely peridot or serpentine within an ultramafic host rock.
Cut Quality
Not applicable (Rough / Uncut specimen).
Brilliance
Low to none in its current rough state; greasy to vitreous luster on exposed crystalline faces.
Fire
None, as dispersion is not visible in this rough green silicate material.
Scintillation
None due to opaque, rough, unfaceted surfaces.
Proportions
Not applicable to raw mineral specimens.
Symmetry
Natural asymmetric rough formation.
Polish
Raw, unpolished surface displaying natural fracture and crystalline textures.
Fluorescence
Unknown without UV testing, though typical silicate minerals in such matrices may show inert or weak fluorescence.
Inclusions
Abundant mineral inclusions, host rock matrix, and natural internal fracturing.
Blemishes
Natural surface roughness, pits, and weathering marks typical of rough stones.
Origin
Likely sourced from ultramafic or ophiolite rock formations associated with tectonic activity.
Treatment Detection
None detected; appears entirely natural and untreated.
Estimated Value
Nominal value as a raw mineral specimen or rough rock sample, highly dependent on precise mineral identification.
Certification Estimate
Not applicable for gem grading labs like GIA; can be analyzed by mineralogical institutions or universities.
Investment Potential
Low investment potential as a commercial gemstone; primarily of interest to mineral collectors.
Similar Diamonds
None, as this specimen is not a diamond.
Setting Suggestions
Wire-wrapped or custom bezel setting if intended to be worn as a raw mineral specimen.
Care & Maintenance
Avoid harsh chemicals, ultrasonic cleaners, and extreme temperature shocks; clean gently with mild soap and water.
Interesting Facts
Green minerals embedded in host matrices often form under high-pressure conditions deep within the Earth's mantle.
