Montreal-based bridal jewelry designer Claude Thibaudeau unveiled a few new creations yesterday at booth LUX636 at LUXURY at JCK. Among the offerings: diamond-accent “semi-mount” bangle bracelets in 18k gold that start at $5,150 retail, and channel-set princess-cut diamond and gemstone inserts for the La Cathedrale and La Royale engagement rings. These inserts or bands can be worn as stacks apart from the engagement ring, and come in six different colors, including black and colorless diamonds, emeralds, and yellow, blue, or pink sapphires. In 18k gold, inserts start at $5,800 with F-G color and VS1 diamonds. All Thibaudeau rings feature a European-style shank for comfort.
