Rembrandt Charms introduced 14k white gold charms, and the resulting "White Hot!" ad campaign last fall. Gumuchian Fils, long known for its luxury designer creations, launched a new bridal collection, featuring 85 hand-finished engagement and wedding bands in platinum. The Touch has created a line of miniature sailor's valentines in 14k yellow or white gold or sterling silver, with or without precious stones. Sailor's valentines originated in the early 19th century, when they were known as shell mosaics.
