23 ct Blue and Violet Sapphire Facet Grade Rough Parcel – 32 pcs Unheated Ceylon Alluvial Rough from Kalawana Sri Lanka

Stone Identity & Quality

This parcel contains 32 pieces of natural blue and violet sapphire facet grade rough with a total weight of 23 carats. Individual pieces range from approximately 0.35 ct to 1.33 ct. The material is sourced from Kalawana village around mining in Sri Lanka, one of the known gemstone-producing regions within Sri Lanka’s sapphire belt. All stones in this parcel are natural and unheated, offered in their original alluvial rough form.

This is a small-size sapphire rough parcel intended for professional cutting evaluation. The material shows a usable range of shape and size for buyers who work with individual pre-form planning and piece-by-piece selection.

Color & Visual Characteristics

The parcel shows a natural spread of blue to violet body color. Some pieces display softer pastel-like tones, while others show more concentrated blue or bluish-violet appearance depending on thickness and light direction. This natural range is common in alluvial sapphire parcels, where each stone carries slightly different color distribution and tone.

Because the sapphires remain unheated, the visible color reflects their current natural state. Final appearance after cutting will depend on orientation, depth retention, and the internal placement of color within each individual stone.

Internal & External Features

Externally, the parcel shows typical alluvial rough surfaces shaped by natural transport and recovery from gem-bearing gravels. The stones display rounded to irregular small rough forms, with natural surface marks, abrasion, and varied outlines consistent with river-worn sapphire material.

Internally, each piece should be evaluated separately. In small sapphire rough, internal openness, zoning, inclusions, and depth balance can differ significantly from stone to stone. That is why parcels like this are usually selected by cutters who understand that structure must be read individually rather than assumed across the full lot.

Cutting & Treatment Potential

This parcel is suitable for buyers looking for small unheated sapphire rough with facet-grade potential. Depending on the internal structure of each piece, some stones may suit compact oval, cushion, or mixed-shape planning. Yield is not fixed and should be judged individually according to shape, color position, and internal condition.

As unheated natural rough, the stones can be studied in their present form before any cutting decision is made. No treatment outcome is assumed or guaranteed. Final cut results depend entirely on the rough selected, the cutter’s mapping strategy, and the balance between yield and appearance.
