24 ct round canary extra brilliant 20 mm This stone is new vintage made under our direction in the 80's. These are much better and closer looking to a real diamond than today's CZ's and moissanite. We sold these quality stones 8 times our Ebay price in our Beverly Hills and Las Vegas stores. Watch the video, these fool jewelers. Better than today's CZ’s, better than Moissanite. Our Secret Jewelers stones were made over 25 years ago with much higher standards than today's diamond imitations. Each stone is equivalent to an E color diamond and are internally flawless. Their brilliance and fire is a testimony to their craftsmanship and longevity. They will last hundreds of years without discoloration. These stones are better than Moissanite. Mossintinte is a generic material.
