Piece of the Week: Cartier’s ‘Black Alley Cat’ Brooch
This carved jasper and yellow-diamond-eyed cat brooch from 1962 is the perfect accessory for Friday the 13th.
Spooky jewelry season is approaching with Halloween only a month away.
With today being Friday the 13th, we’re getting a head start sharing witchy pieces by celebrating this black cat brooch.
While superstitions say black cats are unlucky, many people disagree, adoring the midnight-colored fur of their felines.
Cartier’s “Black Alley Cat” brooch, with fur made of carved jasper and glowing marquise-shaped yellow diamond eyes, went up for action as lot 3 in the offering of more than 190 items in Christie’s “Jewels Online” auction this Wednesday.
As the hammer came down, it sold for $50,400, more than double its pre-sale estimate of $15,000 to $20,200.
The brooch features 18-karat yellow gold hardware on the back that is engraved with “Black Alley Cat.”
The signed piece, circa 1962, comes from the collection of Nina Dyer, a former model who had the brooch made on special order from Cartier Paris, according to Christie’s.
Dyer was known as one of the paramount jewelry collectors of the 20th century, with one of her three-strand black pearl necklaces selling at a 1969 auction for CHF $12.7 million (approximately $14.9 million), after her death in 1965.
She was also known for her love of cats.
Her first husband, Baron Hans Heinrich Thyssen-Bornemisza, gifted her with two black panthers which used to accompany her on her world travels, while her second husband, Prince Sadruddin Aga Khan, gifted her with several Cartier “Great Cat” cuffs, bangles, rings, jabot pins, and brooches.
While the lucky buyer may not be able to take two panthers with them on their world travels, they can still honor Dyer’s love for felines by wearing the Black Alley Cat brooch.
