Colored Transparent Ceramic
Gemstone color · Setting-grade hardness
Doped with rare earth and transition metal ions, our colored transparent ceramic delivers continuously tunable red, green, blue, and yellow hues with brilliant clarity and Mohs hardness up to 9 — a breakthrough material for synthetic gemstones, luxury inlays and fine crafts.
By precisely controlling the doping concentration of Cr³⁺, Co²⁺, Nd³⁺, Er³⁺ and the sintering atmosphere, we produce saturated, high-transmittance colored polycrystalline ceramics.
Applications include premium watch crystals, luxury inlays and bespoke art pieces — combining the visual appeal of natural gemstones with the engineering-grade stability of ceramic materials.
