This premium Flame Fusion synthetic sapphire by Starsgem offers excellent optical clarity and consistency for precision faceting. The colorless, eye-clean material is highly homogeneous and suitable for both classic and custom facet designs.
With an estimated 95% facetable volume, nearly the entire boule can be utilized. Once cut and polished, the colorless material can produce exceptionally bright and brilliant gemstones while allowing the facet design and its reflection patterns to take center stage.
→ The slightly frosted appearance visible on parts of the boule is caused by the unpolished crystal surface. The material itself is transparent and becomes optically clear when properly cut and polished!
