The three auctions were led by an incredibly rare 3.47-carat Fancy Intense Blue Diamond Ring, which sold in yesterday’s Magnificent Jewels auction for $6.7 million – marking a new world auction record price-per-carat for any Fancy Intense Blue diamond ($1,920,259 per-carat).

Representing Fred Leighton’s philosophy to collect the beautiful and eclectic, bidders eagerly vied for pieces evocative of the celebrated jeweler’s unencumbered eye and exceptional taste. Largely formed by his extensive travels around the world, the jewels on offer spanned centuries of design and featured a wide-range of materials including moonstone, demantoid garnets, rubies, emeralds and many more. A Gold, Turquoise and Diamond Grande and Petite Repeating Desk Clock with Alarm by Cartier led the sale when it sold for $275,000 – over three times its high estimate of $80,000.
