Older large 7/8" diameter Navajo silver and 12KGF railed half hoop earrings by Tom Hawk. The silversmith has used three (3) 12K gold wires and two (2) slightly large gauge silver wire mounting them side-by-side on top of a sheet silver base. Forming the mix into a half hoop design and attaching a silver ear stud to one end. The rail style is a typical trademark style of Tom Hawk jewelry.

Each half hoop earring measures 7/8" diameter and are 5/16" wide. They weigh 6.5 grams each (13 grams per pair) and are hallmarked TOM HAWK - STERLING - 1/2012KG.F. by the Navajo silversmith. the equation stands for 1/20th of a millimeter thick of 12K gold filled or attached to in this case sterling silver base. Gold Filled is a way better application than gold wash or gold plated and last almost forever if care for properly. We didn't clean them for the pictures so the separation would stand out in the pictures. They were previously owned, but don't appear to ever been worn. Like New!  $99.95
