    I was in search of a family owned jewelry store on a Sunday & discovered Dejuan Jewelers in Woodland Hills. I noticed a missing diamond in my Mother's ring which I have been wearing since 2000. The ring contained 5 diamonds, one for each of my siblings so it was absolutely precious to me. Both Michael and Sterling listened to my story, assuring me it would be expertly repaired with a matching diamond, beautifully cleaned and ready for pick up end of the week. It was ready 2 days early and was astonished at its polished, gorgeous condition! I was thrilled knowing I made the right decision to trust these two gentlemen Jewelers, both professional, extremely knowledgeable and kind. It was a pleasure working with them, and learning about their passion for this exquisite craft! Robyn Bensinger 10/7/2025
