A sapphire and diamond brooch, circa 1890s, centered with a 14.66-carat, Kashmir sapphire (pictured above) sold for nearly $2.2 million (150,000 per carat), nearly triple its 783,499 high estimate. It was the top lot at Christie’s London Important Jewels sale.
The cushion shaped sapphire is surrounded by an old-cut diamond cluster raised on a scalloped gallery mounted in silver and gold. The auction house said the jewel was from the collection of the late Clive Behrens, and before that part of the collection of the late Evelina Rothschild.
In addition, a sapphire and diamond pendant, circa 1880 (above), centered with a 41.54-carat Burma sapphire sold for more than $1.6 million ($39,000 per carat), more than triple its high estimate of $470,099. The sapphire on the gold plated pendant has an old-cut diamond line border and is further surrounded by cushion shaped diamonds.
Both sapphires show no indications of being heat treated, according to the accompanying reports.
Colored diamonds continue to demand high prices as a ring featuring a crossover design, set with two opposing pear shaped diamonds, a 1.54-carat fancy deep blue and a 1.78-carat fancy intense pink, sold for nearly $1.2 million, well above its $783,499 estimate.
The November 26 auction totaled $22.75 million in sales with 75 percent sold by lot and 89 percent sold by value.
“The London sale of Important Jewels showed that quality, rarity and provenance continue to be the key factors sought by collectors worldwide,” said Keith Penton, head of Christie’s London Jewellery Department.
