2.50 ct Ceylon Natural Unheated Vivid Blue Sapphire Rough from Rambuka, Sri Lanka – Clean Facet Grade Rough

Stone Identity & Quality

This is a 2.50 ct Ceylon Natural Unheated Vivid Blue Sapphire rough measuring 7.1 × 6.4 × 5 mm. The stone is sourced from Rambuka village around mining in Sri Lanka and is presented as clean facet-grade rough. It is a natural sapphire in rough form, suitable for buyers who understand gemstone cutting evaluation, rough planning, color direction, and the transformation process from natural rough to finished gemstone. The stone is currently unheated and shows top quality rough character based on the provided details.

Color & Visual Characteristics

The main visual feature of this sapphire is its vivid blue body color. In rough form, the stone shows strong blue saturation with a lively appearance under light. Thinner areas may display brighter electric-blue transparency, while thicker areas can appear deeper and more concentrated. This type of vivid blue color makes the rough interesting for custom cutting evaluation, but the final face-up color after cutting will depend on orientation, pavilion depth, polish, and how the cutter positions the color within the finished stone.

Internal & External Features

This sapphire rough is described as clean, with a good internal appearance for rough evaluation. It also shows natural rough surface features, which are normal in natural alluvial sapphire material. Before cutting, the stone should be inspected from multiple angles to understand clean areas, surface removal requirements, depth, and the best cutting direction. These details are important because even a clean and attractive rough sapphire must be planned correctly to achieve a balanced finished gemstone.

Cutting, Specimen, or Treatment Potential

As facet-grade rough, this sapphire has practical custom cutting potential. The cutter should study orientation, depth, usable area, surface removal, and final yield before choosing the finished shape. The goal should be to balance vivid blue color, clarity, proportion, and weight retention. This stone may be suitable for a small fine blue sapphire if the cutting plan is handled carefully, but no final result should be guaranteed before professional inspection. Custom cutting and certification can be discussed if suitable.
