I stopped by recently to see if they could repair an Anna Beck Ring. Though they were unable to repair, they gave me some guidance and treated me like royalty while there. They offered me a cold water on that hot day, and even cleaned a diamond necklace I was wearing! It was stunning after they cleaned. I had no idea how dirty it was. The woman that helped me was kind enough to show me a gold shrimp ring that I would love someday. Was a great experience. I'd love to go back and SHOP someday! read more

Mr.Konstantin Kupfer was a great help to me and a Gentleman. I had (2) Rosaries that needed repair and he did a Wonderful job!! Thank you so much read more

Kontstantin really came through for us when we needed an appraisal for a piece of jewelry for insurance purposes. Even though we didn't have an appointment and he was leaving for two weeks the next day, he did the appraisal while we waited. We highly recommend Kupfer Jewelry for any service or purchase. read more

konstantin is a wonderful person who runs an honest great business. He cares for his customers, and above all else, will not try to over charge you or sell you something you don't need. finding an honest jeweler now a days is difficult, but Konstantin is as honest as they come. I would recommend Kupfer to anyone asking for a great jeweler. read more

I had a less than stellar visit at this shop. I brought in a Rolex that I didn't know was real or fake. The owner told me he was sure it was fake but he absolutely could not even touch it because of his "reputation"-- i thought that was odd, like what, am I going to tell all his jewlery industry friends that he touched a fake Rolex and therefore ruin his reputation in the rolex world? . I asked him how he could tell (I was genuinely curious) and he said that he could show me it would say made in China on the inside. He opened it up and showed me it said "made in Japan"- I said thank you. Then he said he normally charges a few hundred to do that for clients but because I didn't believe him, he had to "prove it"--- It seemed a very hostile thing to say, I never asked him to open it and I never said I didn't believe him, I was simply curious as to how one could tell. He could have simply told me to open up the back and I would see, and I could have done it myself- I didn't need him to tell me after the fact that he charges hundreds to show someone a made in japan watch insides. It was an old 1970's watch from a safe and I knew nothing of its origins. He then asked me what was wrong with my 7 year old son who was jumping up and down a bit (but not touching anything as I had instructed my son not to when we entered the store) -I told him my son was fine. Overall the whole experience made me think he was having a bad morning or just a bit full of himself. Not a down to earth experience. I have lots of old gold and jewlery, most real, probably some fake- that I wanted to have assessed, and I am always happy to pay for assessment/valuation services. Its nice when they tell you up front what their fees are, and not do something and try to guilt trip you after like he did me a huge favor. And then making comments about my son was really not polite. I guess I am the only one not enamored with this shop since he has so many good reviews. read more

Outstanding service. Owner is extremely knowledgeable about jewelry and watch repair.

I went to sell one of my items and Konstantin gave me the price I asked for no questions asked. He even cleaned one of my items and commented on the excellent craftsmanship. We also chatted for a little while and we shared the same values. Please, if your looking to purchase any jewelry, stop by and look at his outstanding assortment of fine jewelry, he's honest and fair. You won't be disappointed. If I could give 10 stars, I would. read more

I was extremely pleased with my first and only visit to to Kupfer Fine Jewelry. I felt that I was treated with both honesty and respect during my business transaction. I found Mr. Kupfer to be both personal and focused on meeting my requirements. His brick and mortar was internally constructed and accented with the utmost quality design and craftsmanship as vividly displayed by his product line interior construction. Mr. Kupfer has few peers when it comes to jewelry and precious metal knowledge. I would highly recommend doing business with Mr. K. Kupfer. - M.L.M read more

I recommend this business to anyone looking to purchase or have some jewelry repaired. The owner, Koustanitis, is fantastic to deal with. He stayed late to fix my wedding ring, as I was going to be out of town for a few days. I couldn't be happier with the repair he did. The ring looks brand new . read more

What a great experience I was in about 3 months ago and just thought I would pop in just by chance and found out I could sell him silver my old gold coins a old watch and some other stuff and I got a fair price for them all. He told me what to except so there was no surprises and he paid me cash I was in 7th heaven after leaving and I had mentioned a watch I like and he told me what kind it was and how scarce it was and if I wanted to come back when I was ready he be more than happy to entertain an offer. Well today I can back brought in some gold bars and a bit of cash and got that watch I fell in love with and I was so excited that the price was reasonable and I traded him some gold bars for the watch a small amount of cash and we made a deal right on the spot. I used the gold I brought about 4 years ago and the price was reasonable but I paid far less than the actual price because I had been saving the gold for just this occasion. I got a box and papers which is an extra bonus but that would not matter cause this gentleman is just that I trust him and I left very happy he stayed and got gold and cash and we both had smiles on our faces as I walked out the door. Now since I have done 3 deals with him I trust him more than any jewelry person I have had dealings with and when I get back I will have him make me a ring for our 45th anniversary and it will be gorgeous I know because he has been in this business for so long he knows how to make jewelry how to appraise it how to clean some watches and he ever puts in battery's in watches. He is a man-for all seasons and I would trust him with making my wife her 45th wedding anniversary and know it will be done right the very first time. If u have silver gold old watches or even pens I have seen u will not go wrong going into Kupfer jewelry shop in fact I can almost guarantee u will leave with a very big smile on your face I know I did. read more

I met Konstantin maybe 3 years ago now. I was looking for someone I could trust to fix my dad's watch. I cracked the crystal. I found him online and decided to go into his business and see how I felt about him. I had a bad experience with Kern's and I told him how they made me feel. The moment I walked into his store I felt welcome and I told him that. He looked at my dad's watch and knew instantly how much it meant to me. He said it would be easy to replace the crystal and so I left it with him. A couple of days later I brought in a ring for him to resize for me. I have been going in ever since that first day. This man is amazing. First off he makes you feel welcome in his shop. He always greets you with a smile and I don't know how he does it but his eyes smile too. The energy in the shop is very positive. Sometimes I look at his designs he has created. Everything is done with love you can tell. Sometimes I have gone in there when he has other customers and I hear how happy he makes them feel and it lifts me up to hear such kind words. Some times I go in there to look at his vintage watches or just to say hi. I always leave with a smile on my face and feeling good about myself. Konstantin is the kindest man and I trust him. I try to research things and go back and tell him what I have learned because of something he told me. Because of Konstantin I have started to learn more about vintage watches. I am forever grateful to this man. I am so happy he is in Burlingame. What a gift he is to our community. Thank you Konstantin for all you do for this little town. You are so appreciated. read more

Walked in today and spoke with Konstantin. Did not purchase anything at this time but I'll tell you this...you are in great hands if you plan on doing business with him. He's been in the business 40+ years and is predicated on pure integrity, honesty, and the upmost professionalism. I would not think twice to come back here and spend my hard earned money with this man. Pleasure to meet you Konstantin! read more

I bought in my watch for repair since it stopped working a few weeks ago. Met Konstantin who was extremely friendly and professional. He looked at the watch and he said if parts were needed, the repair may be costly. Given that the watch was relatively a few years worn, he said the watch may still be under warranty and that I should take the watch to an authorized dealer for warranty service. He was 100% correct and the warranty covered the repairs. Konstantin could have repaired the watch at a price, but his willingness to put customers' best interest first, illustrates highly his honesty and integrity. Thank you, Konstantin for the great advice. read more

Great experience with Konstanin!! Just serviced my Rolex Day-Date President and also replaced my dial. It's now Fully reconditioned, polished, with new gaskets etc. The watch looks brand new and it's keeping time flawlessly. Konstanin goes above and beyond to make sure his clients are satisfied. He is a gentleman and very honest - just a good guy. Go deal with him and you'll be happy. He is straightforward and honest, something that I highly appreciate in a businessman. Thank you! read more

Came in for watch batteries. Got one done. However, the owner was very honest and professional, he advised me to send my other watch to the factory for a new battery. He could open it and change the battery but.. that would cause internal damage. He doesn't have a factory key. He could have made more money...Instead, he chose to do the right thing. Thank you for your honesty! I'm happy to support his business in the future. I want to share this with anyone else looking for these types of services. Great to know this is a trust worthy business. Five star read more

We found Konstantin by walking past his shop on Burlingame AVE daily. When we needed a jeweler we wanted to support a local small business and decided to check out Kupfer. After our initial meeting we did some research and found that Konstantin has been providing exceptional service to his clients for years. He is far more than a craftsman and artist - he is a trusted advisor. He is entrusted with the care and upkeep of our wedding bands and has modified existing pieces we have as well as created custom designs using gems we have as well as gorgeous ones he has sourced. I am including photos of some of the pieces he has created for us and am looking forward to having him create a 10 year anniversary band set for us next year. If you are lucky enough to work with Konstantin, you can expected to be treated like family and you will be blown away by the exquisite finished product. We highly recommend Konstantin and Kupfer Jewelry. read more

Thank You Konstantin, my mom said you are a magician and our family friend! read more

Kupfer Jewelry and owner Konstantin was recommended to me by close friend before my engagement and I couldn't be happier with the quality of jewelry and personal service I've received since. He found the perfect rare diamond my wife wanted and created a stunning engagement ring for us. Since then, we had him make custom wedding bands to our exact requirements at a great price. Konstantin is truly a throwback to a classier time where you know your jeweler on a personal level and he is there for you to find the perfect piece for you to commemorate all your life's special events. He even surprised us with flowers and chocolates for the birth of our baby girl and got me a great price on a brand new Cartier Love bracelet as a "push present". Whether you want a custom piece or a great deal on a new name brand item from a luxury brand, Konstantin can deliver at the best price with a hassle free, personal experience! read more

Konstantin is awesome. My husband ordered a vintage Rolex for me for Christmas from a watch dealer on the east coast and when it arrived it was itty bitty and did not come with extra links. I looked up Rolex repair/service and Kupfer was the first place I called. Konstantin answered, I asked if adding links is something he was able to do, along with a few other questions (he is extremely knowledgeable) and he asked me what model the watch was and thought it was doable based on the information I gave him. I went by later that day and get gave me a quote (beyond reasonable) on the number of links needed and said he could have it ready the very next afternoon ! The next MORNING, which was Christmas Eve he text me and said it was ready for pick up! Earlier than promised, and it was perfect. We will only take our watches here to be serviced from now on. I'm so happy we found him read more

Transforming dated heirlooms into stunning signature pieces -- I highly recommend Kupfer Jewelry for exquisite custom work! I inherited a pair of Victorian 'bar brooches' from my grandmother: lovely and quite valuable, but not anything I would ever wear. Konstantin re-imagined them into a pair of gorgeous bangle bracelets, designing band widths that complemented each brooch's dimensions and matching the band metal to that of each brooch. He even checked to make sure they wouldn't interfere with using my laptop trackpad after I mentioned I wanted to wear them as everyday jewelry, not just special-occasion. The finished bracelets beautifully blend antique and contemporary style, and the craftsmanship is outstanding. read more

Konstantin has added many sparkles to our lives this year. We went to him to help make our engagement ring earlier this year. He listened to all of my requests and specifications made me the perfect ring. I've gotten so many compliments from my family, friends, and coworkers on how beautiful my engagement ring is. It has the perfect sparkle and shine. When we were ready to tie the knot later this year, we went back to Konstantin to help make our wedding bands. We were in a rush and needed the rings to be made within 3 weeks with engravings. Konstantin stepped up to the plate and helped to finish our rings in time so we can get married in our forever wedding rings. When we designed the wedding rings, Konstantin was also instrumental in helping my husband select the metal and materials for his ring. He educated us on the firmness of gold vs platinum as well as what color metal would look better on our skin tones. The finished products looked so gorgeous. We even received compliments from our wedding photographers on how much sparkle the rings let off on camera. We also had Konstantin hand engrave my in law's wedding vows onto our wedding bands. The engravings look so clear and precise. On top of that, my husband surprised me with a pair of cushion cut diamond earrings Konstantin made as a wedding present. The color of the diamonds is extraordinary and let off this beautiful shine from afar. We are so amazed by Konstantin's work and cannot have asked for a better jeweler. He is such a pleasure to talk to and is such a subject expert in Jewelery and watches. We can't wait to go back and shop for our 1 year, 5 year, 10 year, 20 year, 30 years, forever anniversary gifts from him. read more

Recently had the pleasure of working with Konstantin at Kupfer Jewelers in Burlingame.

I am very happy to now have a new jeweler to use for my future endeavors. Start your shopping here and you will not be disappointed!! Thanks so much, Konstantin, for the amazing service! read more

Throughout my relationship with my fiancé I always told him I would proudly wear any ring he got for me whether it was fancy or basic because the ring would not determine his love for me. Fast forward to the moment he proposed and I opened the box to see the most stunning engagement ring! I could not believe my eyes it was almost as if I picked it out myself but we never even discussed ring settings or styles! Just completely blew me away. My fiancé and Konstantin worked together and i could not be happier with the ring. The workmanship that went into this ring is so thoughtful. Konstantin was so kind and patient with any follow up and I am really grateful there are honest businesses like his. Side note-- he's one of very very few people who have factory Rolex parts for servicing watches. Just wanted to add a quick edit 07/18/2020 Came in to find a wedding band for my fiancé and Konstantin was more than helpful according to my budget. However, he showed me a one of a kind piece that he personally designed by himself and it blew every other wedding band I've ever seen out of the stadium! I found the perfect wedding band being in the store for five minutes. So cheesy but definitely love at first sight. See for yourself. I almost don't want to post this ring on yelp because it's so unique but something this special must be shared. Photos don't do it justice. read more

Konstantin is the absolute best! Some backstory - my fiancé bought my ring from Brilliant Earth and I got it resized for the first time in June 2022. By August 2022 the ring had completely split open at the resize site. We didn't want to send it in to BE and have to wait 4+ weeks, so we reached out to Konstantin who was highly recommended by a friend. Konstantin mentioned that it would be cheapest to take the ring back to where we got it because he didn't want us to have to pay when it would be likely covered. He was so knowledgeable, let us know that our original jeweler cut my platinum ring with 10k instead of platinum, and they soldered it back together instead of welding it. After hearing how BE treats customers who pay thousand for rings... We do NOT trust them whatsoever so we decided to leave the ring to be fixed by Konstantin & his team. We had the ring band issue and one diamond that had also split on the band (also a BE issue) fixed in less than 2 weeks! You can't see where the ring was welded back together and the new diamond on the band is incredible. We will go to Konstantin for any and all our jewelry needs from this point on. Thank you so much Konstantin! We are such happy customers. read more
