Bonhams auction house was consulted and their jewelry experts sent the stones from the brooch to the GIA. According to National Jeweler: “Bonhams had it tested by the Gemological Institute of America, which confirmed the stones were gem quality. The brooch features an old mine-cut diamond, D color, VS1 clarity, weighing 1.39 carats; a rectangular-shaped emerald originating from Colombia, weighing approximately 1.50 carats; and an oval-shaped Burmese ruby, weighing approximately 0.60 carat.”
Consigned to Bonhams, the brooch was given a pre-sale estimate of $20,000 to $30,000. It will come up for auction on September 19, and OBJ will bring you the results.
But Wait, There’s More…
This kind of once-in-a-lifetime discovery actually happened twice in the last year alone. In June, Sotheby’s London auctioned off a diamond ring which was purchased by the consignee in the 1980s at a “car boot sale” (where people sell items from the trunks of their cars). Assumed for decades to be a fake diamond, it was in fact a 19th century 26.27-carat cushion-shaped white diamond of I color and VVS2 clarity.
It sold for $847,667!
