Vintage Handmade Mexico 925 Black Onyx Sterling Silver Hook Collar Necklace

Vintage Handmade Mexico 925 Black Onyx Sterling Silver Hook & Catch Loop Torque Collar Necklace. From the best I can measure, this collar is 17" around the inside. The pendant measures 2" (including bale) by 1-1/8" wide. It's a large bale for even larger omegas, collars you may have. Collar is 2mm wide. Pre-owned, this vintage necklace is in excellent condition. N608
