If you need custom jewelry or need a jewelry repair, go see Dave! This man is an incredible artist - we needed two very old pieces of costume jewelry repaired - spoke with Dave via phone and he said he would be happy to take a look at them. I brought them to him and not only did he see the issues I was concerned about, but he pointed out something I had not noticed. Very reasonable price for such a great repair - the two pieces look like they have their original backs rather than after-market repairs. We have other items that we'll now take to no one else but Dave for restoration and repair. read more

We came to Dave with bits & pieces of old jewelry, metals & stones we wanted to use in our rings and a couple of ideas with nothing flushed out. My husband had a well loved gold ring given to him by his grandpa. We also found a spool of platinum & a beautiful sapphire hidden in a small medicine box in his other grandfather's machine shop. My husband even had a rock that he hand picked gold from! We brought all of these pieces to Dave & knew we wanted to use them, but weren't quite sure how. So he sat patiently with us and designed exactly what we wanted. It did not take him long at all to make them & they turned out even more beautiful then I could have imagined. Mine is 18k gold with a beautiful unique pattern all around, a platinum bezel & a blue sapphire. My husbands ring is hammered solid platinum with a finger shape band. I have recommended Dave to a lot of people now. I've always loved unique jewelry but I think with something as personal as a wedding ring, getting one custom made is definitely the way to go. I can't imagine being able to design exactly what we wanted and having them made so perfectly anywhere else! read more

We found Dave on yelp and were happy he was local. We went to his home, which was infinitely more comfortable than a jewelry store. He took time with us to listen and help us come up with ideas for our wedding rings. He asked if we had a theme, which inspired us to come up with our idea. He sketched and brought out stones to look at. He is patient and easy to work with. We are thrilled with our beautiful one-of-a-kind rings! I am recommending Dave to everyone!!! read more

I recently had Dave make a wedding band for my new husband and he did a wonderful job. I was trying to have the band match my custom made engagement ring and wedding band. I had a few ideas of how I wanted the ring to look, and when I met with Dave to discuss these, he was able to transform my thoughts into a perfect design for the ring. He was very easy to work with and was very open to suggestions. The ring turned out great. The craftsmanship is really excellent (the ring is stainless steel and is a large, chunky square-shape) and the ring was done on-time. The price was also very reasonable. I would highly recommend Dave. read more

We hired David to design and create an engagement ring for my wife, and then again for a matching wedding band. My wife has a unique and particular sense of style, so this was not an easy task. But David did it. We started by showing him photos, and he came back with pencil sketches. Once he had one we liked, he fleshed out the design with CAD modeling. After more adjustments, we got a lovely unique ring that we both liked, with one large stone and a handful of smaller ones. Though his prices pushed our budget, they were reasonable and below the market rate for what we were getting. Throughout the entire process, we found him pleasant, straight-forward, knowledgeable and very skilled at his craft. read more

David designed a beautiful, unique wedding ring for me. He listened to me and created a piece of art that has so much meaning for me and my future husband. I couldn't be happier, and I highly recommend him. read more

Dave did a fantastic job on our wedding rings. Dave was able to sit down with me on multiple occasions to get the design right. I personally made a mistake that I thought was correct, but thankfully Dave was able to convince me of my error at the last second without making me feel dumb. phew. When I picked them up they looked even better than expected. thanks Dave! read more

I worked with Dave on restoring a 19th c Manchurian Buddha statue - we replaced semi-precious stones in the crown and earrings - he did an excellent job and brought an ocean of ideas to the project that worked beautifully ... he was great to work with, a gentleman, I am looking to create some new projects we can work on together ... he also polished a large bronze mirror for me - he has expert and modest qualities not often found these days read more

Such a nice easy experience working with Dave. I wanted a simple peace sign engraved on my dad's gold crest ring. I was fortunate enough to find Dave after one jeweler failed to give me what I asked for. Dave corrected both engraving and sizing. When I wanted the peace sign tweaked to look more like a traditional peace sign, he made a perfect fix. I LOVE my ring and highly recommend Mercurius. An added bonus...his prices. read more

I comissioned David to create a custom charm for my wife's charm bracelet. There are some animals out there - in this case a Maori Wrasse - that are just impossible to obtain any other way. Anyhow, David at I had good, solid discussions about what I wanted, and we discussed the pros and cons of sculpting the charm versus creating it wih 3D software and making a 3D print. (He is skilled at both.) He was very open about his process and really included me and my input into the process. In the end, what we got was perfect. I enjoyed working with him, and his price was also very reaonable. I'd would recommend his services and would definitely use him again. read more

On a recent trip to Egypt I splurged on a gold charm of my favorite god Set. However when I got him home I felt like he was too fragile to wear. Dave and I worked together to find the right backing on which to put the charm. He really went the distance to find the right piece of lapis and he anchored the charm securely so that now I can wear it with confidence. I really enjoyed working with Dave. His prices are reasonable too. read more

We took my engagement ring to Dave to be resized, and were so appreciative of his work that we had him design and make our wedding bands too! He listened to our ideas (and budget) and helped us flesh out what we wanted because my partner and I didn't really know anything about rings before this experience. Once we had settled on a design, he came in with the rings ahead of schedule to make sure we had them before I went out of town. I would absolutely recommend anyone who wants a personalized jewelry-buying experience in Oakland to visit Mercurius! read more

I initially asked Mercurius for help with designing/finding/making a ring that would feature two stones (set in such a way that didn't look like boobs or a butt). Alisa suggested contacting Little Bird--for which I wrote another positive Yelp review--which helped me narrow down my aesthetic and choices. Then, I took my ideas back to Alisa at Mercurius, who started searching for stones to fit a vintage setting I had purchased. I didn't want anything sparkly, and the stones I went with are not easy to get in a matching pair. She asked great questions that would help her in her search and eventually she was able to find the right stones and send me to the right place to get the work done. I love that every time I wasn't sure what to do, she laid out the options with clarity, patience, and words of support. Dave did the work and the ring is exactly what I wanted for the price I vaguely though I should spend when I started the whole enterprise. I cannot recommend them enough, and I wish I had more occasions to draw upon their expertise and attention. read more

I found Dave through Etsy and contacted him about an engagement ring I wanted to make. I met with him and showed him the rudimentary design I had made after a month tinkering with a CAD program I had downloaded. In 30 minutes, he remade everything I had done, and added the things I wanted to do but lacked the skills for. We iterated on the design a bit, and then he made a really nice wax model, which I used to propose. My now-fiance loved it, and Dave finalized the design and 3D printed the pieces. I wanted to be involved in the process as much as possible, and Dave let me pour the yellow gold into the case (which included a short tutorial and a practice run on an old piece he had). Dave then put all the metal pieces together, carved the red jade I had found, sourced and set he perimeter diamonds, and resized the ring twice. The result is a ring we will cherish for the rest of our lives. Dave is super nice, down-to-earth, and extremely reasonable in his pricing. An amazing jeweler, and a more amazing human being. read more

Dave us awesome! We got our engagement stone on our vacation and worked with Dave to create our engagement ring. He walked us through the process, gave us multiple sketch ideas, etc...The ring is amazing, and we will have him create our wedding bands too. read more

I lost a gold and diamond earring that was part of a set that included a pendant and ring. David made me a duplicate that is so good that I can't tell it from the original - and at a reasonable price. I have some loose opals that I got in Australia and will be going to him about creating settings for them. I also have a silver custom bracelet that I want to have made and will have him do this as well. I can't recommend him too highly. read more

WOW!!! All I keep saying is WOW! I had been wearing and loving my engagement ring for over 5 years but unfortunately the band was very thin and diamonds kept falling out. I got tired of paying for replacements and decided it was time to make my ring more stable. I found Dave on Yelp, sent him a message, heard back the very next day, made an appointment, met at his home to discuss, and 3 weeks later my ring was ready. Dave was wonderful to work with and I am completely blown away by my ring. It is just stunning and I am so glad I found Dave. I would highly recommend him! I could not be happier with my experience. read more

I contacted Dave through his website to ask about getting a matte finish and another minor adjustment to my wedding band, and his response was quick and informative. He was helpful in answering a couple followup questions, and then easy to arrange a meeting with. When I showed him my ring he helped me figure out what to do with it in a way where I could tell I was in good hands. He's clearly a very good listener, but at the same time you can easily trust his knowledge and recommendations. I hung out there while he went back into his shop and made the changes, and sure enough, when he came back out I was an instantly satisfied customer. read more

My wife and I had David make our wedding rings. He was extremely professional and was able to incorporate our ideas and expand on them. He made a finished product that we love, and will be happy to have for the rest of our lives. He was able to facilitate the purchase of our diamonds and platinum at a great price. He was always helpful and informed. read more

My experience with Dave and the ring he made for my fiancée was really great. I first got in contact with Dave in May and explained that I was looking for an engagement ring for my partner, but that I knew very little about rings. I saw the other ads on yelp and thought I would give this guy a try. I went to David's place with an idea of what I wanted the ring to look like and he sketched a couple of different looks, asked me questions about what kind of gold and diamonds I wanted. He gave me a quote later that day. After comparing with some other local jewelry shops, the price seemed pretty competitive, so I went with him. Before finalizing the ring, he made a wax model, to make sure it looked the way I wanted to. I had a really hard time figuring out my partner's ring size, so we kind of guessed at it. The ring turned out beautiful, and my partner really loves it. The ring was actually a little too big for her finger, but it was no problem. We took it back to Dave and he re-sized it for no extra charge. Overall, Dave was really nice and accommodating throughout the whole process. read more

I found Dave online looking for someone who could make allergen-free rings. My wife has a lot of skin allergies and she could not wear her engagement ring because it was causing her to break out. Dave provided us with several options and he was very accommodating when it came to finding convenient locations and times to meet. I replaced my wife's engagement ring, and ordered our wedding bands through Dave. My wife's skin is doing much better, and we couldn't be happier with our rings. Dave even worked with us to design a completely original symbol for our wedding bands that several have complimented. I wouldn't go to anyone else for rings ever again. read more

This is the story of how Dave saved my skin. Many moons ago, my betrothed and I took a class from Dave, learning many secrets of The Other White Metal. (stainless steel. good stuff. ) Under Dave's watchful eye, we crafted our wedding rings. (Really, we took a long time, flailed a bit a the end, and Dave came in and saved our tails then, too, as I recall, but must just be foreshadowing.) Anyway, many years of wedded bliss passed. We found ourselves far from the oceans, and Dave, and then I sort of couldn't find my ring. (it has a pointy bit so I did take it off from time to time.) Argh! In desperation, I dug through my stuff, found Dave's card, found Dave, sent him some measurements and descriptions, (though he remembered spot on the ring and the two of us from way back when) and now very happily and very reasonably I've got my ring back. It is admittedly much nicer than the one I made, but I can delude myself into thinking I might have made something like that from time to time. Nah. So Dave makes beautiful things. And is a lovely man himself. Go to him. You will be happy you did. read more

Love, love, love the earrings that Dave custom-made for me. I wanted to wear special hoops with my fiancé's name and mine on them for our wedding day. They turned out AMAZING I'm so pleased with the look, the weight, and the size of my new hoops. They are going to look so great in pictures and with my dress. If you need anything done, please go and see Dave. Super awesome, personable, and professional! read more

David gave us exactly what we wanted for our wedding rings, even though we had no idea what that was. He listened to our babble of concepts, both physical and metaphorical, asked some questions, gave some advice, drew some sketches and got our feedback, and finally gave us rings we look forward to wearing for the rest of our lives. Due to a miscommunication about dates, he thought he had an extra two weeks to finish the rings, and when he realized the mistake he worked straight through and finished both rings in a couple of days, no problems, no complaints. Absolutely recommended. read more

I called for the first time on a Saturday evening, with a minor jewelry emergency. I wanted a silver chain shortened and a pendant repaired, and I needed it done by Monday. I didn't expect I'd find anyone who could do a repair on Sunday, but I called Mercurius just in case. Not only did Dave answer the phone, he heard how important this was to me, and when he realized he couldn't refer me to anyone else, he agreed to fix it for me right away. He was as pleasant and friendly as could be, didn't charge extra for the "overtime", and I'm so glad I called... read more

Dave made two gorgeous wedding rings for us. My husband had a style in mind, but I came to Dave feeling both vague and picky about what I wanted. He worked with me to come up with an elegant, totally unique design, and fielded my requests to alter it here and there until it somehow morphed into the ring of my dreams. He's patient and kind as well as talented. read more

In town for the weekend and contacted Dave after reading the reviews on Yelp. I had several heavy African bronze/brass metal bracelets that needed to be sized to fit my wrist. I called him and was fortunate enough to be able to schedule an appointment with him that day to show him the bracelets. He was very approachable, knowledgeable, friendly and helpful and let me know what the pros and cons were in working with that type of metal. After our discussion, he sized one of the bracelets on the spot. I was very pleased with the work that he did and would highly recommend him to everyone. Very personable, reasonable and professional. read more
