At OCGEMS, we specialize in the manufacturing of GIA-certified loose polished diamonds ranging from 0.50ct to 3ct, with G–I color and VVS–SI1 clarity. We also collaborate with skilled local artisans to create custom-made diamond jewelry, crafted to your unique style and vision.
We begin by inspecting each rough diamond under 10× magnification to assess its potential.
Advanced tools map out the best shape and cut to maximize brilliance and value.
Precision lasers cut the diamond into carefully planned segments.
The stone is shaped into a round form, preparing it for fine cutting.
