Thank you very much!
Dear Mr. Kleinblatt,
The ring has arrived today. It looks very beautiful (!) and I am really happy with it. I will let you know what my girlfriend did say next week.
I want to thank you and also your colleague Sonja for all the support and good service and for your effort to make the ring arriving in time. I had a lot of fun during the process and it was a pleasure meeting with you and learning the basics of diamonds.
Best regards, Silvio
