Utility patent 1,798,867 (for clip/brooch mechanism) issued to Gaston Candas in 1931 (application filed in 1930); 1950 magazine ad
Gold-plated spirals are adorned with sapphire baguette glass stones and pavé centers on this 1950s Duette, Coro’s name for their double-clip brooch. It is like a “two for one”! Wear it as a brooch or as separate fur clips. The all diamanté version of this piece appeared in a 1950 LifeCoro ad with the slogan “the perfect jewel of a gift” and with the price of $10.50! (In 1950, the average U.S. family income was $81.48 a week.) You can see the utility patent for the brooch mechanism here, shown below Coro’s name.
Two rows of amethyst glass stones separated by two rows of diamanté sit at the center of diamanté-studded folds of rose gold-plated sterling silver that form this 1940s Duetteby Coro. This piece, which was created for Corocraft, the company's high-end line, can be worn as a brooch or as separate fur clips. (Duetteis Coro's name for their double-clip brooch.) My camera picked up two stones that are a different shade of purple, but this difference cannot be seen by the naked eye. You can see the utility patent for the brooch mechanism here, shown below Coro's name.
Marquis-shaped deep sapphire glass stones are accented with round emerald and aquamarine glass stones to form this large late-1950s double-clip brooch and earrings set by the second generation of Hobé designers. An arch of square-cut emerald glass stones at the center of the brooch remains in place when the dress clips are removed from the mechanism. The shape of the dress clips and matching earrings reminds me of Christmas trees. The color combination is late 1950s to 1960s — the early days of Mad Men. This set is definitely unusual!
This bold and beautiful 1950s double- clip brooch by Hattie Carnegie features large cabochon-cut, pear-shaped emerald glass stones, surrounded by round cabochon-cut emerald and ruby glass stones, faux pearls and diamanté. The setting is gold-tone metal. This piece can be worn as a brooch (at different angles, as shown) or as two separate dress clips. The photos show a third option: one clip worn as a pendant on a black rubber cord; you may prefer to use a gold chain. The photos also show how the piece comes apart. Because one of the large emerald stones has lost one of its claws, I strongly advise you to pull the clips apart by grasping the pearl edges. My expert jeweler cleaned and re-glued the affected stone, so it is now secure. A 17-inch, 2mm black rubber cord with a stainless steel twist lock (which is shown in the photo) is included with this purchase.
Loops of diamanté-encrusted ribbons form this Art Deco Clip-Mate, Trifari's version of the double-clip brooch. The setting is rhodium-plated. This piece can be worn as a brooch (at different angles, as shown) or as two separate dress clips. The photos show a third option: one clip worn as a pendant on a black rubber cord; you may prefer to use a silver or white gold chain. A 17-inch, 2mm black rubber cord with a stainless steel twist lock (which is shown in the photo) is included with this purchase. Wear this piece with faux or real diamond studs for an added touch of sparkle. You can see the utility patent for the brooch mechanism here, shown below Trifari's name.
