“So I don't know if it was my fault for not reading the material it was made out of. I did that after I bought it. But I've had a different pura vida ring (wave ring) for 6 years and it has never changed colors or left a mark whether I'm surfing, showering, or whatever. However, this Rising Sun Ring instantly has darkened and leaves a slightly back residue on my finger. I'm just a little bummed because I wear my rings 24/7 even while surfing. I love Pura Vida, just bummed they don't keep using sterling silver as their rings.”
