Sapphire Ingots
Product Highlights
Our Ingots are cored from our HEM grown boules after the boules have been sliced and
graded by our technicians. The ingots are cored on A-axis using precision CNC coring machines.
The ingots are then inspected for any defects and trimmed to length. The crystal axis is measured and the ingots are precision ground to final diameter.
Final quality inspections are performed before packing and shipping.
