Natural rough mineral crystal (likely beryl, tourmaline, or quartz rather than a standard diamond due to color and crystal habit; assuming industrial or specimen context)
Natural rough mineral crystal (likely beryl, tourmaline, or quartz rather than a standard diamond due to color and crystal habit; assuming industrial or specimen context) · Rough uncut crystal / elongated prism form
Not applicable (Rough, unpolished crystal) Cut

Carat
Estimated 15-25 carats based on visual volume
Color
Light green / pale greenish-grey
Clarity
Included / opaque to translucent (I3 equivalent for rough specimen)
Shape
Rough uncut crystal / elongated prism form
Overall Assessment
An interesting raw mineral specimen in a natural rough state, possessing character typical of unworked pegmatite minerals rather than a faceted diamond
Cut Quality
Not applicable (Rough, unpolished crystal)
Brilliance
Low due to opaque nature and lack of cut facets
Fire
Minimal to none in current rough state
Scintillation
None
Proportions
Elongated prismatic crystal habit
Symmetry
Natural crystal symmetry showing striations
Polish
Raw, unpolished matrix and crystal faces
Fluorescence
Unknown without UV testing
Inclusions
Heavy internal fractures, mineral inclusions, and surface dirt/matrix
Blemishes
Natural surface etching, striations, and pitting
Origin
Natural rough crystal from a pegmatite or metamorphic deposit
Treatment Detection
None detected; appears entirely untreated in rough form
Estimated Value
Low commercial value as a gemstone; valued primarily as a mineral specimen ($20 - $100 USD)
Certification Estimate
Gemological lab certificate as a mineral specimen rather than a cut gemstone (e.g., GIA Identification Report)
Investment Potential
Low investment potential; more suited for mineral collectors
Similar Diamonds
Comparable to low-grade industrial rough or mineral specimens
Setting Suggestions
Wire-wrapped pendant or custom organic bezel setting if polished as a cabochon
Care & Maintenance
Gentle cleaning with warm soapy water and a soft brush; avoid harsh chemicals and ultrasonic cleaners due to internal fractures
Interesting Facts
Rough crystals retain their natural geological history, showing growth lines and striations formed deep within the earth
