Natural GEUDA Sapphire Rough from Sri Lanka

Discover natural GEUDA sapphire rough, a distinctive type of natural corundum widely recognised in Sri Lanka’s gemstone industry. GEUDA is a local trade term commonly used for certain cloudy, milky or hazy-looking sapphire rough.

This material attracts interest from gemstone cutters, rough gemstone traders and heat-treatment specialists because selected GEUDA stones may develop improved colour and transparency through controlled heating.

Characteristics of GEUDA Sapphire Rough

Natural GEUDA sapphire rough can display different appearances depending on its original formation and internal characteristics.

Important features include:

GEUDA Sapphire Heat-Treatment Potential

Selected GEUDA sapphire rough may respond to specialised heat treatment, potentially improving colour and transparency. The final outcome depends on the individual stone’s chemical composition, inclusions and heating conditions.

Not all GEUDA rough is suitable for successful treatment, and the final result cannot be guaranteed before processing.
