Carved from mammoth ivory and holding a pearl, this frog makes an enchanting ring.  It appears to be a one off design by Bibi van der Velden – no size is indicated and it just says “unique” under “sizing”.  It’s a bit ironic that this ring echoes the
Cinderella story – either your finger will fit this frog prince, or it won’t. Yours for about $2100 at LuisaViaRoma.
