Congratulations to the newly engaged couple! ✨

Michael shared such kind words about their experience:

“Jahan brought the right blend of warmth, patience, and experience to the ring design process, which led us to a ring that surpassed our expectations. First, Jahan carefully listened to Roxanna's preferences for her diamond and her ring design. Then, he found the perfect European-cut center stone that matched Roxanna's dream diamond. Roxanna was over the moon and surprised when Michael proposed, considering Jahan finished the ring early!"

We’re honored to have played a small part in such a meaningful moment.
