The object in the image is not a diamond. It appears to be a natural rough stone, likely a variety of chalcedony like banded agate or a similar silicate mineral.

N/A (Uncut/Rough stone) Cut
Carat
Estimated 5-10 carats based on size relative to the carpet fibers.
Color
Non-diamond color; brownish-beige with white banding (Agate pattern).
Clarity
Opaque to translucent; not graded on a diamond scale.
Shape
Rough / Uncut / Irregular
Overall Assessment
This is a common natural stone, not a diamond. It is identifiable by its distinct banding, waxy luster, and lack of diamond-specific optical properties.
Cut Quality
N/A (Uncut/Rough stone)
Brilliance
None; surface is matte/waxy.
Fire
None.
Scintillation
None.
Proportions
N/A
Symmetry
N/A
Polish
None; natural weathered/raw surface.
Fluorescence
Likely None or inert, typical of common silicates.
Inclusions
Internal banding visible (concentric/parallel layers) characteristic of agate.
Blemishes
Natural fractures and surface erosion consistent with outdoor find or decorative gravel.
Origin
Terrestrial; likely riverbed or sedimentary deposit origin.
Treatment Detection
None detected; appears to be raw mineral.
Estimated Value
Minimal; likely a nominal value of less than $1 USD as a garden or landscape stone.
Certification Estimate
Unlikely to be certified by GIA/IGI as a diamond; could be identified as Agate by a gem lab.
Investment Potential
None as a gemstone.
Similar Diamonds
None; it lacks the refractive index and crystal structure of a diamond.
Setting Suggestions
Not suitable for jewelry without tumbling or professional lapidary cutting.
Care & Maintenance
Wash with soap and water; very durable as it is likely quartz-based (hardness ~7).
Interesting Facts
The banding suggests it is a piece of agate, which is formed by the deposition of silica from groundwater in the cavities of igneous rocks.
