Here is a 675 ct, 45 mm, synthetic ruby cut by Eric Bardawil from giant boules grown by Union Carbide in the 1980s. These crystals were intended for use in the lasers of the Strategic Defense Initiative (the so called “Star Wars” program), which never came to fruition. This is the largest faceted synthetic corundum I have seen anywhere and if not the largest ever, it must certainly be near the top of the list. It is perfect and completely loupe clean. Just sharing and not for sale.
