Natural rough diamond crystal

Natural rough diamond crystal · Uncut octahedral / irregular rough crystal

Not applicable (rough, uncut stone) Cut

Natural rough diamond crystal - Uncut octahedral / irregular rough crystal

Carat

Estimated 2.5 to 3.5 carats

Color

Near-colorless to faint yellow (approx. G-I range)

Clarity

Estimated SI1 to SI2 based on visible internal features

Shape

Uncut octahedral / irregular rough crystal

Overall Assessment

A promising natural rough diamond crystal with good clarity potential, well-suited for bespoke organic jewelry or professional cutting to maximize value.

Cut Quality

Not applicable (rough, uncut stone)

Brilliance

Low due to rough, unpolished surface

Fire

Minimal due to lack of faceted geometry

Scintillation

Absent prior to cutting and faceting

Proportions

Not applicable to rough crystals

Symmetry

Natural octahedral crystal symmetry, slightly distorted

Polish

Natural crystal faces (trigons and growth lines visible)

Fluorescence

Cannot be determined without UV testing (estimated None to Faint)

Inclusions

Possible small pinpoints, feathers, and cloud clusters typical of rough diamonds

Blemishes

Natural surface etch marks, striations, and trigons

Origin

Likely from primary pipe deposits (South Africa, Canada, or Russia)

Treatment Detection

No signs of artificial treatment; completely untreated natural rough

Estimated Value

Varies widely by weight and exact internal clarity; roughly $3,000 - $6,000 USD for rough stone

Certification Estimate

GIA or IGI would classify this as a rough gem-quality diamond

Investment Potential

Moderate, highly dependent on the final yield and cut grade if faceted

Similar Diamonds

Comparable to standard run-of-mine gem-quality octahedral rough crystals

Setting Suggestions

Can be custom-set in a raw diamond organic gold bezel setting, or polished into a brilliant cut

Care & Maintenance

Standard warm soapy water and soft brush; rough stones are durable but edges can chip

Interesting Facts

Shows natural growth features and crystal habit typical of carbon crystallization under high pressure and temperature
