Just beautiful, Love this color.

Beautiful color. Looks great in my sister's wedding ring!

I have been ordering blanks and inlay from this place for over a year quality products super fast shipping and great prices over 50 blanks not one issue

I received my items rather late and when I received it, one item was damaged. I reached out to Opal and was immediately assisted by providing me with a replacement as well as a very sincere apology for the delay in receiving the package.

Would absolutely purchase from them again and highly recommend them.
