Approximately 25mm overall. We loved these vintage brass components (item 26602) so much, we had them plated in silver. They came out of the E.A. Adams warehouse that closed many years ago. Designers like Miriam Haskell used this type of component within their jewelry fashions. Please check out the vintage chatons (items 9060-9065) we have found that fit these settings perfectly. These stampings have filigree styled leaves and holes for swidging onto other pieces. Lot's of options for attaching these pretty findings to your work. Add some bling to them or use them as is. You can even dangle these findings. There are so many design possibilities.
