Natural Rough Crystal (Mineral Specimen)

Natural Rough Crystal (Mineral Specimen) · Natural Elongated Hexagonal/Prismatic (Uncut)

N/A (Rough/Raw Specimen) Cut

Natural Rough Crystal (Mineral Specimen) - Natural Elongated Hexagonal/Prismatic (Uncut)

Carat

Estimated 1.5 - 3.0 carats based on finger scale

Color

Faint Brown to Grayish-White (Near-colorless but included)

Clarity

I2-I3 (Opaque to Translucent with heavy internal inclusions)

Shape

Natural Elongated Hexagonal/Prismatic (Uncut)

Overall Assessment

This is a low-quality natural mineral specimen, likely a diamond, quartz, or light-colored sapphire. Its high level of inclusions and irregular shape make it unsuitable for high-quality gemstones, but it holds interest as a raw geological sample.

Cut Quality

N/A (Rough/Raw Specimen)

Brilliance

Low (Light is trapped by rough surface and internal inclusions)

Fire

Very Low (Mineral does not possess dispersive facets)

Scintillation

Minimal (Only visible at surface contact points)

Proportions

Elongated prismatic structure with natural growth striations

Symmetry

Poor (Natural crystal unevenness)

Polish

N/A (Rough surface finish)

Fluorescence

Cannot be determined without UV light source

Inclusions

Heavy veining, clouds, and possible carbon spots visible

Blemishes

Natural surface etchings and contact marks from mining

Origin

Likely alluvial or volcanic secondary deposit (found in soil/gravel)

Treatment Detection

No visible signs of treatment; appears in raw, natural state

Estimated Value

$10 - $50 (Minimal value as an uncut, low-clarity specimen)

Certification Estimate

GIA Rough Diamond Identification Report or Geological Mineral Report

Investment Potential

Low (Lacks the clarity and size for high-end faceting or resale)

Similar Diamonds

Compare to industrial-grade rough or raw bort diamonds

Setting Suggestions

Wire-wrapped pendant or rustic prong setting for raw mineral jewelry

Care & Maintenance

Ultrasonic cleaning is discouraged due to potential fractures; use warm soapy water and a soft brush

Interesting Facts

The elongated shape suggests a hexagonal crystal system similar to quartz or sapphire, though it may be a heavily worn diamond macle or elongated crystal.
