Konstantin is an amazing artist and craftsman. His attention to detail is remarkable; nothing is good enough for him until it is *perfect*. I was so lucky to find him when looking for someone to make some very unique cicada earrings based on another design, because he was so patient and careful with the process, making sure that I was completely happy with every step until the final product arrived. When I did see the final pieces, I was blown away. They were far better than my wildest dreams! He worked and reworked them until they were beautiful and still light enough to be totally comfortable. I loved them so much, I knew immediately that I had to ask Konstantin to make my wedding bands for my fiance and myself. I cant wait to see what he will do! Please do yourself a favor and see what this man can do, it is really amazing!

Found Kupfer via online reviews for a luxury watch battery replacement. Konstantinos was very courteous, professional and replaced the battery on the spot for a very reasonable price. This would normally cost 2x and take approximately 3 days elsewhere.Its great to have a small family run business on Burlingame Avenue.

Konstantin knows his trade well. Have purchased several pre-owned watches from him along with his excellent service ( Rolex, Omega, etc ) with my other watches. He will give give you his expert opinion and has saved me on more than one occasion making a bad trade. Highly recommended.

Great place, fixed my chain! Excellent service and quality.

Fine jewelry and watches with an old world watch maker at the helm. I would not trust my watch to anyone else and have been happy with the jewelry I have purchased over the years. Great place to find very special gifts.

Got an engagement ring made here. Konstantin made it from scratch after I gave him an idea of what I was looking for. The ring was spectacular and for the price I got a super deal. Best purchase ever. Konstantin will take care of you and make sure you are happy with your purchase.

Popped in for a battery change for my watch... the service was top notch and friendly. Highly recommend.

Very knowledgeable and you can tell they wants to educate the clients as oppose to just getting a sale

I walked in this place a few years ago And met Konstantin, and the first thing I asked him if he could help me with a Jewlery gift for my wife. He went above and beyond in taking care of me within my budget and have been going to him since. Phenomenal customer service and beautiful Jewlery.My next purchase, a Rolex for my Birthday.
