You are buying 12 of 18x13mm Victorian Shiny Gold Plated Closed Loops Pendant Settings 27x21mm. These settings are originally from the 1900-1930's, I only had a few left and found a company to make these for me. They were made in the USA, 1990's and the company is out of business. The design is just delicate, but they are very solid, not flimsy like others are. There is an art deco look to them, they are a nice size pendant for a 18x13 mm setting. The outer dimensions are 27x21mm. These are sturdy. You will not be disappointed in the quality, it is excellent. Please look at all the pictures, Smoke and Pet Free.
