Counted among Mother Nature’s most incredible creations, a rare colored diamond is considered by many to be the most coveted of all gemstones. Those colored stones that are graded as fancy colored diamonds and higher are distinguished even further and can often be exponentially more scarce than even the finest diamonds, especially examples weighing over 5.00 carats. At M.S. Rau Antiques, we are pleased to offer a superb selection of the very rarest and most important colored diamond rings, colored diamond necklaces, bracelets and earrings, including blue, green, yellow and pink estate diamond rings and other estate diamond jewelry.
