Ahmed I know you already knew it was coming but I wanted you to be one of the first to know…Dave proposed to me in Venice today and I said yes! I was so surprised when it happened. I was so amazed to learn that you hand selected the sapphires for my engagement ring. Your gems have been such an important part of our love story and I’m very honored to have them on another piece of jewelry from my (now) Fiancé! Thank you so much for your hard work in helping Dave pull off this amazing surprise!! 🥰
