DALLAS, TX.- Investment-caliber gems and stunning pieces from rare designers are among the top attractions in Heritage Auctions' Fall Fine Jewelry Auction Sept. 23 in Beverly Hills, California.

Among the rare designers spotlighted in the sale are Marchak, Sterlé, Flato, Taffin, Jean Vendome and Verdura.

"This is an exceptional auction, because there is such a wide range of beautiful, high-quality jewelry,” Heritage Auctions Senior Director of Fine Jewelry Jill Burgum said. "The sale has an outstanding selection of pieces by rare artists, but also features some stunning pieces, from investment-level gems to some gorgeous curiosities that rarely reach the auction block.”

A dazzling Ceylon Sapphire, Platinum Ring, Dubail Paris, French (estimate: $100,000-150,000) boasts a square cushion-shaped sapphire weighing 28.45 carats, set in platinum and marked Dubail Paris, with French hallmarks. The ring is accompanied by a 2019 AGL report that states "Natural Corundum, Sapphire, Origin Ceylon (Sri Lanka), No Gemological Evidence of Heat, No Clarity Enhancement.”

A Diamond, Emerald, Black Onyx, White Gold Bracelet, Cartier, French (estimate: $50,000-70,000) features full-cut diamonds weighing 4.33 carats, enhanced by carved black onyx accented by pear-shaped emeralds for the eyes. The Panthère bracelet's gems are set in 18k white gold, marked Cartier, with French hallmarks.

An Antique Black Opal, Diamond, Enamel, Platinum, Gold Brooch, Marcus & Co. (estimate: $10,000-15,000) is a beautiful turn-of-the-century piece from the designer whose firm rose to prominence early in the 20th century after Dresden jeweler Hermann Marcus partnered with his son, William, in 1884. The piece is exceptional because it is rare to find a piece this old with an opal in such good condition. The brooch's oval-shaped black opal cabochon is enhanced by European and rose-cut diamonds, complemented by champlevé enamel, set in 14k gold with platinum accents, partially marked M. & Co.
