N3. A 130.50-carat Burmese Sapphire and Diamond Brooch – $7,127,453
As we climb the top, the gems will be more expensive and their weights will increase.
For example, this Burmese Sapphire and Diamond Brooch weights 130.50 carats.
This brooch has a rose-cut diamond surround and collet-set old-cut diamond frame organized in silver and gold.
It used to hold the record for the highest price sapphire sold at auction until it was broken last November.
The Burmese Sapphire and Diamond Brooch was sold at Christie’s auctions in Geneva on May 2011.
Its color, the royal blue comes from a combination of well-balanced trace elements in the stone and from the characteristics for the finest sapphires of the Mogok gemstone line.
