The dazzle begins on April 25 with pieces from the Estate of Bo Legendre, as well as several stunning examples of jewelry by Suzanne Belperron (1900-1983). Known for being something of a modernist at a time when Art Deco reigned, Belperron was one of the first female master jewelers of the 20th century. Famously, she never signed her pieces, which means one must have an eye for Belperron, although a certificate of authentication, like the one that accompanies this citrine and diamond cuff, circa 1945, certainly helps!

In the middle of the 20th century, Oscar Heyman & Brothers was a fixture on Fifth Avenue, excelling in diamond brooches, rings, and necklaces set in platinum. This Art Deco brooch from the 1930s—featured in Fortuna’s April 26 auction—adds beautifully carved rubies, emeralds, and sapphires to the mix.

Finally, a different sort of gorgeous is expressed in this rare Rolex Daytona Cosmograph, serial number 8617084, which dates it to 1985. While the material of the timepiece itself is not especially precious—it’s made out of stainless steel—the precision of the Rolex Valjoux caliber 727 manual wind movement inside is a form of elegance all its own. It, too, will be available from Fortuna on April 26.
