A 17.43-carat Kashmir sapphire previously owned by a European noble family will go on sale at Bonhams later this month.

The cushion-shaped, vivid-blue stone, which dates to the late 19th or early 20th century, will lead the April 30 sale in London, the first time it has appeared at auction. It is expected to fetch GBP 300,000 to GBP 400,000 ($391,080 to $521,440).

“Sapphires hailing from Kashmir are among the most highly prized gems for serious connoisseurs,” Emily Barber, director of jewelry at Bonhams UK, said last week. “After the discovery of the mine in the high Himalayan mountain region of northwest India in 1881, the majority of mining activity took place during the following decade, after which the supply was essentially exhausted. This makes them extremely rare.”

The sale will also include a step-cut, 9.07-carat, F-color diamond ring, which has the potential for VVS1 clarity. That piece is valued at GBP 250,000 to GBP 350,000 ($325,900 to $456,260).

A transformable diamond and sapphire necklace by designer Grassy will also go under the hammer. The articulated collar can be worn as is, or in one of four other ways: the 34.59-carat sapphire detaches and can function as a ring; the entire center plaque of the necklace can be removed and worn as a clip; and the detachable plaque clasp can be worn either as a clip or in the center of the necklace. It carries a presale value of GBP 120,000 to GBP 180,000 ($156,430 to $234,650).

In addition, Bonhams will auction a ring featuring a step-cut, 22.02-carat, Colombian emerald sitting on a mount formed by two marquise and brilliant-cut diamond honeybees and two brilliant-cut diamond leaves. The jewel, signed by both Tiffany & Co. and designer Jean Schlumberger, was part of the collection of artist Andy Warhol. It is estimated at GBP 65,000 to GBP 85,000 ($84,730 to $110,810).
