Artisanal jewelry is a great way of adding to your collection and having pieces that not everyone else will be wearing.
These earrings by Elisa Bongfeldt are made of cast and fabricated sterling silver using (it seems) yellow enamel and an oxidized finish to the metal.
They sell for USD$787.

that seems awfully expensive for silver and enamel. I’d like them better if the silver was bright. That would give more of a summery light to the design, which I do like, I just think the asking price is high.
Agree it’s a lot for silver but I am thinking the casting process for a piece like that would be time consuming and take some skill.
