Very pretty I just ordered a half size too big
Absolutely stunning. Pictures do not do these rings justice
Love this ring it is amazing. The only thing I wish is that they came in half sizes. I am a 6.5 and my options were smaller or bigger and now I need to get it adjusted. Otherwise love it!
So beautiful✨
Beautiful set! My partner and I are absolutely in love with them! Sizing was perfect, I was a little nervous when ordering online and not being able to test fit as rings I’ve gotten online in the past weren’t true to size, but these are! Very comfortable to wear as well. I couldn’t be happier!
