  • 1.75 ct Sapphire New Vintage Genuine Corundum Swiss Made Synthetic Stone 7.5 m

    1.5 ct Round Sapphire. (7 mm). This is a new vintage synthetic sapphire made in the 80's under our direction. The material is corundum made in the lab. The hardness is 8.5. The chemical content is very close to a real sapphire. If you own a Rolex watch with an indestructible sapphire crystal the material is the same corundum without color. The color on this stone is a dark deep blue. Each stone was hand cut an looks incredible. These stones have been sitting in a vault untouched and we are offering them at a fraction of their original price. We sold these in our Beverly Hills and Las Vegas stone for over 100.00 per carat. Due to the nature of these stones, it is very difficult to capture the exact color and the flash slightly lightens the color.
