Great services done here when a diamond fell out of my engagement ring. I had bought the ring in another state and had no idea where to go. When I spoke with Danielle I instantly felt at ease letting a "stranger" fix my most prized possession. I got my ring back and it's as beautiful as the day I said I do which was 5 years ago! They made it like new! I hope to not need anymore repair work but if I do there is no question where I would go. Also, while I was in their office I could see what they had for sale and everything was stunning and so well priced.

Bob Santucci and his team at West Coast Diamond and Gem are absolutely sensational. My now fiance and I went in with a design I'd roughly devised in my mind. With Bob's expertise, exceptional conversation, and customer service, I ended up with the ring of my dreams on my hand. Bob was able to bring life to the custom ring I'd imagined. The process was simple and enjoyable, with no upselling in sight. Bob put in all the work to ensure the most stunning diamond and setting within our budget. If you're looking for second to none experience when buying jewelry for your partner, friends, or family, I can assure you all of your needs will be met, and your expectations exceeded, at WCDG.

Bob and his team are the best in class. He guided me through the diamond selection process and made it a point to ensure I was getting the absolute best quality diamond in a price point I was comfortable. After selecting the diamond, I took his advise and went to 5 different competitors to compare. Bob's selection was far better than any of the others I saw. After I selected the diamond, I brought my fiance in to meet Bob and discuss the setting.
She and Bob hit it off from the start. Bob was able to create the exact setting that she wanted and 5 years later my wife loves staring at the ring. We highly recommend Bob to anyone shopping for a ring.
