Had my grandfathers wedding ring resized for myself at Preziosi and I'm glad I finally went! Gian, the owner, was very accommodating and explained the process in great detail. I was going up three sizes and didn't even know if he could do it. Gian is very good at his trade and assured me it would be perfect! He was right! He totally had to cut the ring and add more gold but I couldn't even tell where he did that!

His craftsmanship is impeccable.not only was the work absolutely perfect he was very reasonable with his pricing! I took a look around at the shop when I was there and he has an amazing selection of jewelry, Definitely coming back! Thank you Gian!

Wifey needed her watch battery replace. We stopped in at Preziosi's, knocked on the door and we were buzzed in. The owner is super nice, replaced the battery in no time flat, and set the time for her. $15 charge. Preziosi sells quality jewelry ranging from approximately $1,000 to, high end exceeding $49,000 Sorry out of respect for the owner I chose not to take pictures of the inside.

This is where you want to go for a beautiful new piece of jewelry! I recently purchased a diamond ring at Preziosi. I told Gianluca that I was looking for something modern and "airy." You may not think that this store would have designs that are somewhat out of the box, but they do. Gianluca showed me 5 or 6 rings and I chose a gorgeous diamond ring. Preziosi also has inventory at all price points and beautiful watches. Be sure to ask to see his wife's family's jewelry.they've been making jewelry in Italy for 9 generations! Enjoy browsing and shopping at this Los Altos gem.

I went in right when the store opened, because I was so excited for my new watch and needed to get it sized. The gentleman helping me was quick and had great/warm customer service! I will definitely go back!
