Love the ring but it stains!

I was so excited when I got this bath bomb! I thought it was such a good idea and I couldn’t wait to use it. But when I did the bath was great and my ring was gorgeous; all was amazing until I got out and drained the tub. My entire bathtub was stained grey and it took me 4 washes to finally get the stain out!! I had to scrub it and use a deep cleaner to get it all out. It also stained my skin!! My body was all grey and it took a few showers with an exfoliant to get it all off!!! The jewelry is beautiful but it definitely isn’t worth all the extra work
