Natural Diamond (Industrial Grade / Bort) - Rough / Polished Spherical Bead

Carat

Estimated 0.50 to 0.75 ct

Color

Off-white to light yellow / gray

Clarity

I3 / Heavily Included

Shape

Rough / Polished Spherical Bead

Overall Assessment

This specimen is a heavily included, low-grade natural diamond shaped into a bead, primarily suited for industrial applications rather than jewelry

Cut Quality

Poor (Non-standard bead shape)

Brilliance

Very low due to heavy internal inclusions and opacity

Fire

Minimal to none

Scintillation

Poor, lacks standard facet-based light return

Proportions

Non-standard proportions due to bead form

Symmetry

Poor (Irregular spherical form)

Polish

Low luster polish typical of bead cutting

Fluorescence

Indeterminate from visual assessment

Inclusions

Dense internal cloudiness, numerous pinpoints, and feathers throughout

Blemishes

Surface pits, natural remnants, and abrasion marks

Origin

Natural rough source, likely Africa, Russia, or Australia

Treatment Detection

No obvious signs of artificial treatments, appears as-mined low-grade rough

Estimated Value

Nominal value ($10 - $50 USD depending on industrial use)

Certification Estimate

Unlikely to be certified by major labs like GIA or AGS due to industrial/low quality

Investment Potential

None; industrial-grade rough diamonds do not appreciate as investment assets

Similar Diamonds

Industrial diamond beads, low-grade natural bort, diamond powder source material

Setting Suggestions

Not recommended for fine jewelry settings; suitable for specialized industrial tools or experimental pieces

Care & Maintenance

Standard care; though durable, it is structurally compromised by heavy inclusions

Interesting Facts

Most natural diamonds mined are of industrial grade rather than gem quality and are used for cutting, grinding, and drilling
