  • We originally came to TQ Diamonds on the recommendation of a friend - and it didn't disappoint! We worked with Ted from our selection of my engagement ring all the way through to my husband's and my wedding bands. Ted was patient with us as we carefully selected and sifted through all their beautiful engagement ring options and even worked with us on how to make my perfect ring (of course above our price range) fit into our budget. We were able to customize the stone on top of the setting to make my ring unique to me and the most beautiful representation of my personality and our love for one another. I still get compliments on how beautiful my ring is...with repeat offenders! :) And when my wedding band we ordered didn't fit perfectly with my engagement ring, Ted recognized the error right away without question and worked with the jeweler to fix it and order another band. Echoing my friend's recommendation - I am passing it on!
