First - I LOVE their security measures in place, having the control to unlock the door for their customers. It made us feel safe, especially with all the recent jewelry store robberies that have been going on in the Bay Area. Upon entry, we were greeted with warm personalities and smiles from the three ladies behind the counter. They never pressured us and allowed us time to look around. When we were ready, one of the sale clerks came over to help us. We explained that we wanted a simple, single, white gold band, and then selected a diamond. She laid out everything for us to look at and when she dropped the diamond on the setting, my heart knew it was the one I wanted. The diamond is 2.10 karats, and it's simply breathtaking! We did not trade in my wedding ring, it was a purchase for my right hand and a "I'll love you more than forever" ring from my husband. We opened a credit account and it was so easy, with six months interest free! We highly recommend the Jewelry Exchange in Redwood City for all your jewelry needs! Especially if you are purchasing an engagement ring, or wedding set! We also got my wedding rings from this same store, 18 years ago and they are still holding strong. The customer service and attention we received in this store was nothing short of AMAZING!

Exceptional Craftsmanship and Unparalleled Customer Service!…read more I highly recommend The Jewelry Exchange in Redwood City for any custom jewelry needs. Four years ago, my husband and I commissioned them to design my original wedding ring, and the craftsmanship was exceptional. Unfortunately, I misplaced the ring some time ago. To surprise me for our fourth anniversary, my husband wanted to replace it, so we immediately returned to The Jewelry Exchange. Once again, they delivered outstanding results. I chose a design to mirror my original ring, and the team replicated it phenomenally. They assisted me in selecting the ideal diamond and precisely executed my vision. I am incredibly pleased with the final outcome. The customer service here is truly unmatched. Herout and Lilibeth provided consistent updates regarding design modifications, ensured I approved the layouts, and confirmed that every detail aligned with my requests. Rena and the rest of the staff were always friendly, welcoming, and deeply attentive to our needs. I am completely satisfied with their work and look forward to returning for future purchases. If you visit, I highly recommend requesting Herout for your consultation. Five out of five stars. Their service is excellent and their execution is flawless. Thank you so much!

And don't overlook this jeweler if you have a repair or appraisal need. I recommend this jeweler 100% to anyone in the market for fine jewelry. He also buys! 2 thumbs up to Daniel

They provided an estimate of cost for the resizing (and complimentary cleaning) prior to me agreeing to moving forward with the service. Yubi was the employee who helped me, and he was just the sweetest and most professional. They gave me a rather quick timeline - only four days or so, and it was done in two. Which is much quicker than I've experienced in the past at other stores. The quality of the resizing was very well done, and the ring is sparkling clean. I also thought the price was within my expected estimated range given that the ring was very wide and gold. While there I also purchased a pair of earrings. They were also wonderfully helpful and kind with that experience as well. If I ever need jewelry again, I'll be going back there and would 100% recommend their services.
