How accurate is their sizing? Should i go up a half size for thr stacking?

For me, each individual ring fits spot on, but with 3 rings interlocked together and because occasionally my hands swell just enough, it sometimes gets too tight on my finger. So I'm ordering a half size up to fit better.

I purchased one of these two years ago, and it just started to give me a rash. Can anyone confirm these are not just coated in silver?

It is platinum plated... but it its sterling silver under the platinum plating. When I first got mine after a couple weeks of wearing it daily I noticed that the plating was peeling off... but never did it turn my finger colors or anything. When I came back to read the description again I noticed that it does say that its platinum plated over .925 sterling silver...

does this make your finger turn green?

Green finger free! I bought mine in March of 2021 and is still in awesome shape & condition. I recommend this company in all. All of the rings are nice but this one is my top favorite. So I never take my of my rings off. I have worn this one since I bought it. I wear this ring in the shower, washing dishes, even gone in the pool with it. This ring is 100% sterling silver, has the 925 imprinted inside the ring. (SideNote) Also Great for those of us who deal with any anxiety, nervousness etc. it’s a great ring to twist/turn around your finger while stressed. If that makes sense. We’ll I hope my review was helpful. Happy shopping 😉

Are you sure this is sterling silver ? i bought one and it doesn’t look like ss also i bought my granddaughter 1 & after 2 days of wearing it her

It is .925 sterling silver with a platinum plating over. I've had mine for almost 2 years and the plating did start to peel off a few months after I had been wearing it daily... it never turned my finger green & usually if I put fake jewelry on within an hour of wearing it my finger gets discolored... 2 years later... the platinum plating wore off but since it was genuine .925 sterling silver it looks as good as new.
