Dear Jenny,
Yesterday was a blissful dream. I woke up and felt like a newlywed. I can’t stop looking at my diamond ring. You were nothing short of a gift to me. We instantly connected and I felt a strong pull you were going to the one who found me my ring. I’m so over the moon and eternally grateful. You are incredibly talented at what you do. Tyler and I feel like we not only found the ring to symbolize who we are as a couple today, it embodies everything we didn’t even know we were looking for and that’s life’s best surprise sometimes. The happiness this ring brings to me leaves me speechless.
Thank you for all you do—you are one in a million.
Nicole J.

My ring is drop dead gorgeous!!! I don’t care if it has inclusions it still has so much fire and sparkle! Only if you loop it can you tell... that makes this a fantastic deal. It was sized extremely professionally, I’m thrilled, what a statement huh? Thank you for your upbeat spirit
