Rough Quartz or Common Glass (Potential Diamond Simulant)

Rough Quartz or Common Glass (Potential Diamond Simulant) · Irregular / Rough (Uncut)

N/A (Rough/Raw specimen) Cut

Rough Quartz or Common Glass (Potential Diamond Simulant) - Irregular / Rough (Uncut)

Carat

Estimated 8.00 - 15.00 carats (based on size relative to fingers)

Color

Near Colorless (Estimated I-J range if compared to diamond scale)

Clarity

Included (Contains visible fractures and internal veining)

Shape

Irregular / Rough (Uncut)

Overall Assessment

This specimen is highly unlikely to be a diamond. It lacks the characteristic isometric crystal habit of a diamond and displays fractures typical of silica-based materials like quartz or glass. It serves as a visual simulant but lacks the physical properties of a gemstone.

Cut Quality

N/A (Rough/Raw specimen)

Brilliance

Low (Due to lack of faceted surfaces)

Fire

None visible (Specimen exhibits low dispersion)

Scintillation

Poor (Surface reflection only)

Proportions

N/A (Raw state lacks geometric proportions)

Symmetry

N/A (Natural irregular form)

Polish

N/A (Natural surface texture)

Fluorescence

Indeterminable without UV light

Inclusions

Large internal fractures, planes of cleavage, and possible fluid inclusions

Blemishes

Surface abrasions, conchoidal fracturing, and impact marks

Origin

Terrestrial (Commonly found in alluvial deposits or as industrial debris)

Treatment Detection

None apparent; looks like raw mineral matter

Estimated Value

$5 - $50 (Typical for raw quartz or decorative glass fragments)

Certification Estimate

Unlikely to be certified by GIA/AGS as a diamond; would require a colored stone identification report

Investment Potential

None (Low-value common material)

Similar Diamonds

None (This specimen lacks the adamantine luster and crystal habit of a natural rough diamond)

Setting Suggestions

Wire-wrapped pendant or kept as a raw mineral specimen

Care & Maintenance

Avoid heavy impact; wash with warm soapy water

Interesting Facts

The conchoidal (shell-like) fracture visible on the edges is a primary indicator of quartz or glass rather than diamond, which has octahedral cleavage.
