8.20 ct Ceylon Golden-Brown Zircon Rough with Salmon-Red Color Shift – Bibilegama Sri Lanka

Stone Identity & Quality

This is an 8.20 ct Facet Grade Ceylon Natural Zircon rough measuring 12.9 × 9.7 × 5.9 mm. It was sourced from Bibilegama village around mining in Sri Lanka.

The stone is naturally alluvial, showing the rounded external character associated with transport through gem-bearing gravels. Its body appears clean and transparent according to the supplied evaluation, giving the rough good potential for professional faceting.

Color & Visual Characteristics

The main body color is golden brown. Under fluorescent illumination, this golden-brown appearance is dominant, while incandescent or warmer lighting produces a noticeable movement toward salmon red.

Because the difference is visible but relatively moderate, the most accurate description is:

Golden-brown to salmon-red color shift.

This lighting-dependent behavior gives the rough additional visual character, but the final appearance after cutting will depend on orientation, depth, facet arrangement and how light travels through the finished stone.

Internal & External Features

The zircon shows a relatively clean transparent body together with a naturally worn alluvial exterior.

Its surface carries natural texture and small marks resulting from its geological journey before recovery. These external features must be considered during preforming because some surface material will need to be removed before the final facet design is established.

The internal transparency gives a cutter an opportunity to study:

Color direction

Clean areas

Depth

Surface removal

Possible orientation

Potential weight retention

Final face-up color

No finished clarity grade should be assigned while the material remains rough.

Cutting, Specimen, or Treatment Potential

This zircon is presented as facet-grade rough, so its primary interest is cutting.

The natural shape provides useful body and depth for evaluating a finished gemstone, but the final design should not be selected only by trying to preserve maximum weight. A professional cutter should balance weight retention with brilliance, symmetry, durability and color presentation.

The subtle color shift also makes orientation important. Different cutting directions may influence whether the finished stone emphasizes the golden-brown side, the warmer salmon-red response, or a balance between the two.

Final carat weight, brilliance and finished color cannot be guaranteed before cutting.

Source & Ethical Position

Danushka Gems & Minings works directly through Sri Lankan gemstone-producing areas and local source networks, allowing natural rough stones to be evaluated close to their mining and trading origins.

This zircon was sourced from Bibilegama village around mining in Sri Lanka. Our approach is to describe rough gemstones realistically—showing the actual body color, transparency, natural surface, lighting response and cutting potential without guaranteeing an outcome that can only be known after cutting.

This gives gem cutters, dealers, collectors, jewelers and international buyers a clearer understanding of the material before deciding how the stone should continue its journey.
