So helpful
COOs were great. We bought our rings from them and they were great during the selection process and so knowledgable. I also had my engagement ring cleaned before the big day and it came back looking as good as new!

Beautiful custom wedding band to fit my engagement ring
My engagement ring was my grandmother's Victorian ring and is quite an unusual wave shape, which meant a straight band wouldn't work. COO were so helpful right from the start at talking with me about what was possible and making a band within my budget that was a perfect fit to my engagement ring. They were also great when one of the smaller diamonds on my grandmothers ring fell out (it's pretty old after all!) and got it professionally secured again at no extra cost. Really happy with the end result!
