True artisan jewelers who have integrity and non-cookie cutter designs and ideas. John has been on College Ave for 45 years. I LOVE my rings he's designed. Highly recommend!

Wow! Best place in bay area to get your jewellery. people here know their work best I was facing so many issues with my ring, the stone kept getting loose again and again and they fixed it so well. They suggested the ways in which this can be fixed and did a brilliant job at a reasonable price.very very happy with the service.

Were so very helpful with choosing a replacement stone for a ring. Beautiful work. Reinforced the prongs as well. Very reasonably priced.

I love this store. Incredible, beautiful jewelry. Made in shop. Friendly and welcoming shopkeepers. A resident dog. Full length mirror. Recycled jeans made into dog collars and leashes. What more could you want? Yes. They have that too.

They resized my palladium ring, very reasonable price and I think I got it back within a week. Would go here again for jewelry work!

The people that run this place are amazing. I bought my wife's wedding ring here a couple years ago (a beautiful, unique piece that I hadn't seen anywhere else), and I still get amazing service from them even though I've long since moved away from the Bay Area. I've been able to contact them by email to do upkeep by sending the ring in, and we walked in the other day because we happened to be in town and they were able to service the ring again in no time. Amazing service and products!

What can I say about this place that hasn't been said before? A great place for custom jewelry at good prices. All of my friends and I have had our wedding rings custom made at the 14 karats. Great service and attention to detail at good prices.

Awesome jewelry shop that is both local and family owned. I got my wife's engagement ring crafted with them and I loved how quickly they worked and the quality of the ring. We got our wedding rings from 14 karats too and have been coming back every year for all of our fine jewelry needs despite the fact that we are no longer living in the Bay Are. Seriously, you can't get a better value anywhere else!
