Christie’s Geneva will offer the jewelry collection of Hélène Rochas, wife and muse of the late fashion designer Marcel Rochas, on November 12, 2013 as part of its Magnificent Jewels auction. The 18-piece collection includes a ruby brooch by Van Cleef & Arpels (estimate: $190,000-$255,000), a rare leaping tiger brooch by Rene Boivin (estimate: $190,000-$255,000) and a pink topaz, aquamarine and diamond bangle by Verdura (estimate: $127,000-$190,000).

Rochas, who passed away in 2011, also maintained an impressive art collection that included works by Edouard Vuillard, Wassily Kandinsky and four portraits of herself by Andy Warhol. In 2012, Christie’s Paris organized a sale of her art holdings, which ended up breaking four world records.

Besides Rochas’ collection, the jewelry sale will include pieces once belonging to Bolivian tycoon Simón Iturri Patiño. Highlights include an emerald and diamond necklace by Cartier London (estimate: $7 million-$10 million) and a cushion-shaped F-color diamond ring of 32.65 carats by Chaumet (estimate: $2.2 million-$2.8 million).
