This beautifully carved opal bust pin hails from the Art Nouveau period of the turn of the century, is mounted on a 14K rose gold stick, and comes in the original green velvet fitted box. Overall, this makes for a great purchase for a collector of antique pins. The box is marked Georgetown, KY, from the jeweler & optician, S.E. Bahlow, giving you a piece of Kentucky history. It would give a jacket an extraordinarily dignified look. And if you were born in October, opal is your birthstone, which makes this piece a must have.
