Princess cut synthetic Sapphire
A jewelers needed a princess cut white Sapphire for his customer for a custom ring they were building. His customer didn't care if it was genuine or synthetic and they were in a bit of a hurry to find the material for genuine stone, so they decided to go with the synthetic. I had the material in stock, so we could do it quickly for them.
Below, you will see photos and description of the cutting process.
