This necklace shows the longitude, latitude for a location. Necklaces are hand cut and hand stamped from silver plated metal, and hangs from sterling silver chain. I oxidize the surface, then polish it to create the blackened letters. Necklaces are custom made. When you check out, leave me a note and let me know the city and state or country you want the coordinates for. And if you would like 16 inch or 18 inch chain.
