Owned by one family since the 1950s, the ring soared to more than double its pre-sale estimate to $873,000. The sapphires were a classic example of the cornflower-blue stones from the famed Kashmir mines, before they closed in the 1880s.

Another rare colored stone was an antique Burma ruby ring. The exceptional red color and clarity of the stone attracted bidders from all over the world. The ruby sold for $171,000, more than twenty times its conservative pre-sale estimate.

Antique and Period Jewelry

Antique jewelry continues to be a top category at Skinner. The cover lot of the Important Jewelry auction was a 19th century diamond sunburst brooch from the famed jewelry collector and socialite Hope Goddard Iselin. The sunburst form was popular in the Victorian era, but the large scale of this example was unique. It sold for $61,000, at the high end of its presale estimate. Etruscan revival jewelry remains popular, especially examples by famed Italian jeweler Castellani. A gold and glass grapevine necklace is a classic example of his work and drew spirited bidding to reach its final price of $43,000.
