5.60 ct Ceylon Natural Unheated Bi-Color Spinel Rough from Pathakada, Sri Lanka – Facet Grade Alluvial Bluish-Violet & Pink-Purple Spinel

Stone Identity & Quality

This is a 5.60 ct Ceylon Natural Unheated Bi-Color Spinel rough measuring 11.5 × 9.1 × 5.2 mm. The stone is sourced from Pathakada village around mining in Sri Lanka and is presented as facet-grade alluvial rough. It shows a natural combination of bluish-violet body color and a pink-purple color zone near one corner. Its size, depth, and color zoning make it suitable for professional custom cutting evaluation by gem cutters, dealers, collectors, jewelers, and international gemstone buyers.

Color & Visual Characteristics

The main body color of this spinel appears bluish-violet, with a visible pink-purple zone toward one corner of the rough. This natural color combination gives the stone a bi-color appearance in rough form. Under light, the bluish-violet body can appear soft and open, while the pink-purple area adds a warmer color contrast. The final face-up color after cutting will depend strongly on orientation, cutting angles, depth, and how the cutter positions the color zone within the finished gemstone.

Internal & External Features

This spinel rough shows a natural alluvial surface with rounded form and surface texture from Sri Lanka’s gem-bearing environment. The external shape gives useful material for cutting study, while the internal color zoning is the main feature to consider during planning. The pink-purple corner should be studied carefully so the cutter can decide whether to preserve it as part of a bi-color design or orient the stone for a more blended violet-blue appearance. Any surface-near marks, clean areas, and depth should be checked before pre-forming.

Cutting, Specimen, or Treatment Potential

As facet-grade rough, this spinel can be studied for a custom faceted gemstone. The 11.5 × 9.1 × 5.2 mm size gives the cutter room to consider different shapes depending on the best orientation. Because the stone has natural bi-color zoning, the cutting decision should focus on color placement, clean area, weight retention, and final face-up balance. A carefully planned cut may highlight both the bluish-violet body and the pink-purple zone, but no final color result, shape, or finished weight should be promised before physical inspection and cutting study. Custom cutting and certification can be arranged if suitable.
