in the last weekThe folks here are always so accommodating. I've had them repair a couple of items and provide estimates, and they've been very professional. Their jewelry inventory is gorgeous and includes styles I've never seen elsewhere.

in the last weekGeoffrey’s is my “go to” spot for jewelry repairs I’ve needed (ring resizing, necklace chain repair). I have also purchased a special pieces (gemstone ring, freshwater pearl earrings) that were chosen carefully with the help of the keen eyes, knowledgeable and friendly staff. I have come away with keepsakes within my budget. It is a beautiful place to visit and I appreciate the free ring cleaning!

in the last weekI had another great experience at Geoffrey’s Diamond Shop in San Carlos. Sunny, who helped me months ago, was amazing again, and her colleague who assisted me today was wonderful as well. They made picking out the perfect birthday gift for my wife easy and enjoyable. Great selection of diamonds and beautiful jewelry, Highly recommend!

a week agoI have always had a great experience with Sonny and Nikko. I started coming to Geoffrey’s when they were at the original location and have followed them ever since. Very trustworthy, which means a lot to me. My daughter also had a great experience with Erica designing her wedding band.
