Silver and blue Pura Vida ring

From Pura Vida's April 2023 jewelry subscription - brand new and not even taken out of the packaging. No clue what the stone is but it's a pretty purple-blue (I have the earrings, just haven't worn them yet. if you're searching for them, let me know!). The ring is a size 9 and other than my engagment ring, I don't wear many rings.
