The Mandalay Ruby
The Mandalay Ruby is one of the most impressive ruby in the world: What has made his fame is its weight: 48,019ct, and its origin: the Mogok Mine in Myanmar which is the best deposit for rubies. Its origin gives a very nice hue and an extreme clarity : it has an intense red that is close to the “pigeon blood red”, the most sought after color for rubies, and is almost flawless. Its weighs 48,019ct and has been estimated at $15 millions by Sotheby’s in October 1988, but because of the lack of bidders at the auction, the Mogok Ruby didn't find any buyer. Although it comes from Mogok, the ruby is called “the Mandalay” because it is the name of the historical city and last royal capital of Myanmar, 60 miles away from the Mogok Mine.
The Carmen Lucia Ruby
This Mogok Ruby weighs 21,3ct and is set in a platinum ring, surrounded by diamonds. The gorgeous vivid red is enhanced by the extraordinary transparency of the stone and its cut. This ring has been ordered and donated to the National Museum of Natural History of NYC by Peter Buck - nuclear physician and wealthy co-founder of Subway restaurant - in memory of his beloved wife.
The Graff Ruby
The English jeweler Laurence Graff bought a cushion cut Burmese ruby of 8,2ct for $3,6 million at Christie’s auction in 2006. Graff is famous for buying a lot of the most beautiful diamonds that have been sold at auctions. With his unique talent, Graff set the Burmese ruby into a ring, that he probably sold to the Sultan of Brunei, a loyal customer of Laurence Graff since his beginning. The Ruby is still considered as more valuable and rare than high-quality diamond: one of the reason is that ruby deposits are rarer than diamond deposits and high quality ruby deposit are even rarer. The other main reason why it is more valuable than diamond is that the colorformer of the ruby is Chromium, which gives a really nice red to the stone, but also curbs/slows its growth : a big ruby is really exceptional and prices rise really quickly. The “record” dates back to 1988, when Sotheby’s sold a 16ct ruby for $227,301 per carat...
