When I wear this necklace everyone says it looks like the Olympic Rings...hence the name. All metal is 14 gauge. The middle circle is the largest and gold filled. Soldered to each side is a rose gold and silver ring. Soldered to the rose gold filled is the smallest gold filled. The chain is 1.4mm gold filled. If you'd like a different combination, please message me and I can make it happen. This necklace is handmade by me and the exact size and angles may differ slightly. Please inquire if you have any questions. Thanks for checking out my listing!
