{"product_id":"unheated-thai-ruby-ring-4-74-carats","title":"Unheated Thai Ruby Ring, 4.74 Carats","description":"The 4.74-carat oval shaped brilliant cut ruby at the center of the ring is a remarkable rarity. The accompanying Gubelin report confirms its completely unheated state, meaning its vibrant color is entirely natural. Large, gem-quality rubies are rarely found in nature, and most are treated to enhance their quality, making this example truly remarkable. The report also includes an information sheet attesting to the gem's exceptional rarity, with an outstanding rating from the gem lab. Originating from Thailand, the ruby is beautifully complemented by 3.00 carats of diamonds, which surround the stone in a halo and form a unique band of marquise shaped stones. Set in 18K white gold. \u003cbr\u003e\u003cbr\u003e \u003ca href=\"http:\/\/library.rauantiques.com\/Report_32-0405.pdf\" target=\"_blank\"\u003eDownload the Report\u003c\/a\u003e","brand":"M.S.
