Glassmakers in late nineteenth century Bohemia (later Czechoslovakia) were the first to develop the method of press-molding glass buttons and jewelry stones. At first they molded solid colors of glass, but as their skills developed, they began to imitate multi-colored stones like opals and tortoiseshell. The blue, red, green, and gold confetti stone at the bottom of this necklace represents the height of their lampworking and press molding skills. From the 1930s on, Japanese artisans began to press mold glass cabochons, and sapphire and emerald glass cabochons with goldfuss or goldstone sparkles were made by them. In this piece, from the top: Small antique hammered brass button, circa 1880-1900 Two lampworked and hand-pressed goldfuss or goldstone cabochons in sapphire and emerald glass, made in midcentury Japan Lampworked and hand-pressed confetti opal cabochon, made in midcentury Czechoslovakia Four brass-plated pewter settings made in the US Antiqued brass chain Length: 16-20"
