John, we received the ring today, March 25.
Thank you so so much for your kindness and generosity!
Your assessment we to believe is correct. 
The Jeweler selected an outstanding stone. 
We don’t know a lot about opals,
but we think the refractory qualities of this stone are truly great. 
We will prize this ring for the rest of our lives. 
Not only for the beauty, but for the story behind it. 
We hope our paths can cross again someday. 
We will never forget you and Australian Opal Cutters. 
Every opportunity that presents itself, we will recommend our acquaintances to visit your business.

Sincerely

Mr. R & Ms. D
