21.75 ct Ceylon Natural Unheated Pastel Blue to Violet Sapphire Rough from Endana, Sri Lanka – Facet Grade Alluvial Rough

Stone Identity & Quality

This is a Ceylon Natural Unheated Sapphire rough weighing 21.75 ct and measuring 17.3 × 13.7 × 11.5 mm. The stone is sourced from Endana village around mining in Sri Lanka and is presented as facet-grade alluvial rough. It has strong size, useful depth, and natural internal features that make it suitable for professional cutting evaluation by gem cutters, dealers, and buyers who understand rough sapphire planning.

Color & Visual Characteristics

The stone shows a soft pastel blue body color with a slight violet appearance under different light sources. Under fluorescent-type light, the stone may show a cooler blue tone, while under warmer incandescent light, the violet side may become more noticeable. This should be described as a slight light-dependent visual shift, not as a guaranteed certified color-change result.

Internal & External Features

This sapphire rough contains visible small crystal inclusions inside, along with natural alluvial surface marks and internal structure. These features should be studied carefully before cutting because they can affect orientation, clean area selection, final clarity, and yield. The rough surface and internal characteristics are part of the natural identity of the stone.

Cutting, Specimen, or Treatment Potential

As facet-grade rough, this stone has custom cutting potential, but the final result should only be decided after proper cutter analysis. The cutter should study the color direction, depth, clean areas, inclusion placement, and best orientation before choosing the final shape. Because the stone has good size and depth, it offers planning possibilities, but no finished weight, color, or clarity result should be promised before cutting.
