This 14-Karat Gold Tie Tac makes a bold and striking statement of effective brevity. The body of the tie tac is oblong, made of highly polished 14-karat gold. Leaving only a frame of gold is a smooth black onyx inlay. The enigmatic depths of the onyx contrast with the luster of the gold. This tie tac will keep your tie neat and professionally stylish, and is compactly sized at 3/8 inches.
