57.60 ct Ceylon Natural Mixed-Color Spinel Rough Parcel – 25 Facet Grade Alluvial Pieces from Sri Lanka

Stone Identity & Quality

This parcel contains 25 pieces of natural Ceylon spinel rough with a combined weight of 57.60 ct. Individual stones range from approximately 3.00 ct to 1.40 ct.

The parcel is sourced from Marapana and Hangamuwa village around mining in Sri Lanka and consists of naturally occurring alluvial rough. The stones are presented as facet-grade material and, according to the supplied information, are unheated.

The parcel contains several naturally occurring spinel colors, giving cutters and dealers the opportunity to evaluate different materials within one source-connected collection.

Color & Visual Characteristics

The rough stones display a varied natural palette including pink, reddish-pink, purple, violet, gray and blue tones.

Some pieces show relatively concentrated color, while others reveal softer or mixed tonal appearances depending on lighting, thickness and viewing direction. Because these stones remain uncut, their final face-up color cannot be determined solely from their rough appearance.

Correct orientation will be important for balancing color, brightness, finished depth and weight retention.

Several reddish pieces also show red fluorescence when exposed to short-wave ultraviolet light. This is an interesting gemological response, particularly when comparing the different colors within the parcel. However, fluorescence intensity can vary between individual stones and should be considered one observation rather than a standalone identification test.

Internal & External Features

These are natural alluvial rough stones, so their surfaces show rounded, water-worn forms and individual natural markings created before recovery from gem-bearing gravels.

Across the parcel, buyers and cutters should evaluate:

Transparency and clarity

Internal inclusions

Color concentration

Possible zoning

Surface-reaching features

Natural fractures

Usable depth

Orientation

Expected cutting yield

Fluorescence response where present

No finished clarity grades are assigned because the stones remain in rough form.

Cutting, Specimen, or Treatment Potential

This parcel is presented as facet-grade spinel rough, making professional cutting the primary potential use.

The individual alluvial shapes provide different opportunities for oval, cushion, round, pear, mixed and other practical designs depending on each stone. The final shape should be selected after examining the cleanest body area, color direction, inclusions and available depth.

Exact finished weight, clarity, brilliance or recovery cannot be guaranteed before preforming and cutting. Each stone should therefore be planned independently rather than applying one estimated recovery percentage to the complete parcel.

Custom cutting and certification can be discussed for suitable material.

Source & Ethical Position

Danushka Gems & Minings works directly with gemstone-producing areas throughout Sri Lanka, including source-connected travel and sourcing from mining communities and local gem networks.

This parcel comes from Marapana and Hangamuwa village around mining in Sri Lanka. Our approach is to present rough gemstones with practical information about source, color, condition, treatment status and cutting potential rather than making unrealistic promises about final results.

For international buyers, gem cutters, dealers, jewelers and collectors, this allows each rough stone to be evaluated on its real characteristics before deciding the next stage of its journey.
