Natural Diamond (likely type IIa based on strong blue fluorescence under UV light, though visual assessment from a single blurry photo is limited) - Indeterminate / Rough or Raw Crystal (elongated crystal habit visible)

Carat

Estimated 0.50 - 1.00 carat based on visual context

Color

Near colorless to faint blue / variable due to photographic lighting

Clarity

SI1 - SI2 (Estimated based on visible localized inclusions)

Shape

Indeterminate / Rough or Raw Crystal (elongated crystal habit visible)

Overall Assessment

An intriguing natural rough diamond crystal displaying prominent blue fluorescence under specific lighting conditions. While lacking the optical performance of a faceted stone, its raw and natural aesthetic holds unique charm for mineral collectors.

Cut Quality

Not applicable (Rough, unpolished crystal)

Brilliance

Low to moderate, typical of unpolished or rough crystalline surfaces

Fire

Limited dispersion due to lack of standard facet angles

Scintillation

Minimal standard scintillation; exhibits localized intense fluorescence glow

Proportions

Natural rough proportions, uncut crystal morphology

Symmetry

Natural crystal symmetry (octahedral tendencies)

Polish

Unpolished natural crystal faces (surfaces show natural striations or trigons)

Fluorescence

Strong Blue (strongly visible reacting to ambient or UV light sources in the photo)

Inclusions

Internal dark spots and cloud-like pinpoint inclusions visible near the illuminated tip

Blemishes

Natural surface features, etch channels, and possible trigons on rough faces

Origin

Natural rough diamond, potentially from African or Canadian primary deposits

Treatment Detection

No evidence of artificial treatments; appears completely untreated and natural

Estimated Value

Varies widely based on exact weight, purity, and market demand for rough specimens ($500 - $3,000 USD)

Certification Estimate

GIA or AGS if submitted for full analytical grading report

Investment Potential

Niche market appeal; high value for collectors of rough minerals and unique natural crystals

Similar Diamonds

Other unpolished octahedral or elongated rough diamond crystals with strong blue fluorescence

Setting Suggestions

Organic bezel setting or raw gemstone prong setting in yellow or white gold to preserve the natural crystal form

Care & Maintenance

Clean with warm soapy water and a soft brush; avoid harsh chemicals and ultrasonic cleaners if internal fractures are present

Interesting Facts

Strong blue fluorescence in natural diamonds is often caused by sub-microscopic aggregates of boron or nitrogen-vacancy centers within the crystal lattice
