I don't have the pave pendant but it seems to be the easiest to wear and will last the test of time. Even the back of the pendant has a nice design that I've heard can be worn front-facing for a different look.
Guilloche is a fine choice for earrings! We all need to start somewhereAnd you will probably collect more in the future. Are you not planning on anymore VCA earrings?
I'm already making a list, but I want to approach each purchase with the goal of maximizing usage and making sure the items will coordinate down the road and that I won't get tired of them. I didn't know that about the back of the pave pendant! Good to know!
