Chrysmela Catch and Chrysmela Extra are the identical earring backs. The only difference is the removable disc which is included in Chrysmela Extra for lift and additional support.  Oh, and easier handling.

We introduced Chrysmela Extra for customers who are used to using a disc type earring back.  For larger diamond studs, it lifts them to the best placement.  Chrysmela is strong and secure enough alone to hold even your heaviest statement earrings. But some delicate earlobes may benefit from the extra support of Chrysmela Extra.
