Vintage Retro ~1ct Sapphire & Diamond Platinum Engagement Ring Sz 5 5.7g Estate
Hallmarked platinum and the stones test as sapphire and diamond with a presidium gem tester. I do not know if the sapphire is heat treated or natural but it’s a lovely color and clarity and the straight bands of color zoning seen on magnification would insinuate it is a natural sapphire.
