Sotheby’s auctions two diamonds over 100 carats – JCK

On June 16, Sotheby’s will auction two diamonds over 100 cts. to her Gorgeous jewelry sale in New York, including a legendary gem.

The first, the Juno, is a 101.41 ct. pear-shaped D internally flawless and is expected to gross over $10 million. Also on sale is the Earth Star, a famous coin of 111.59 ct. deep orange-brown pear-shaped fancy diamond.

In a statement, Sotheby’s hailed the Juno as the “fourth largest pear-shaped diamond of its type to be offered at auction.”

“Pear-shaped diamonds are particularly sought-after members of the 100 ct. club,” the auction house added, “because they are easier to wear than other shapes, making them perfect pendants for statement necklaces.

The Juno is a type IIA diamond, extremely rare in natural stones. It is named after the ancient Roman queen of the gods, who was considered the goddess of light and fertility.

Regarding the Earth Star, Sotheby’s noted that brown diamonds of this size, in cut and polished form, are extremely rare, with only three diamonds over 100 carats ever at auction. This is the second largest.

The Earth star was listed in Lord Ian Balfour’s authoritative book Famous Diamonds. Sotheby’s will offer it without reservation, but with an estimate of 1.5 to 2.5 million dollars. For this auction, jeweler David Webb fashioned a custom setting using the azure malachite gemstone, to resemble Earth seen from the perspective of a star.

The original piece of rough, weighing over 248 cts, was discovered at the Jagersfontein mine in South Africa in 1967. In 1983 it was sold for almost a million dollars and has remained in private hands ever since, making it the first time the diamond has appeared on the market in almost 40 years.
