We are a family-owned and operated jewelry business in the town of Los Altos dedicated to bringing our clients beautiful jewelry, value, and excellent service. Much of our collection has been imported from Italy by us. A growing portion of our pieces are custom designed for our clients. Our store has been known as Rancho Jewelers for more than 65 years and has been in our family since 1987.
We service Rolex, Omega, Patek Philippe, Cartier and most other fine watches. Bay Area Checkbook, a consumer magazine, rated us very highly in their watch repair study. We replace movements in many moderately priced watches. We can also replace watch batteries, watch bands, and can perform some minor repairs while you wait, such as new crystal, new stem, new crown, etc.
Diamonds are the most purchased and most sought after gems in the jewelry world today. A wedding diamond is the most important and enduring symbol of a couple's love and is also one of the most mysterious purchases a man makes in his lifetime. We pride ourselves in taking the mystery out of buying a diamond without losing the magic.
We specialize in platinum and 18 karat gold jewelry. We have a selection of pieces in yellow, white, and rose color golds. The diamonds and gemstones that we keep in our inventory are of very high quality. We strive to offer jewelry of very high quality, both in design and craftsmanship, and at a fair price.

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!

So i needed to have a couple of links removed and the bracelet clasp re-set in a new steel Rolex. Not difficult by any means, but it has to be done correctly and without damaging the bracelet or case. i called Preziosi (regrettably i don't remember the gentleman's name, but i believe he's the owner) and he said could do it, just bring the watch in. so i show up at 1620, 40 minutes before closing time.

I show him what i want done and he said "no problem, give me about 10 or 15 minutes" i returned then, he handed me the re-sized watch and the two links in a small plastic bag; he waited for me to try it on--perfect fit. I said "thank you", and "how much do i owe you" he told me $10. I have paid $50 for the same thing--and this was without 15-minute turnaround--so i gave him $20 and he only reluctantly accepted it according to the (glowing) yelp reviews for this shop, this gentleman is quite a skilled maker of custom jewelry.

But sometimes those guys act make you feel like a jackass when you show up with a trivial little task like re-sizing a watch bracelet. But not this shop in the future, if i need to purchase an engagement ring, new watch strap, jewelry for gifts, an appraisal, etc. this is where i go.

Went in to get new batteries for my watches and get some repaired. The owner gave me a great deal and got it all done in an hour. I had never been in the shop before and it is worth mentioning that they have a beautiful collection of jewelry from Italy. Lots of special pieces of the highest quality craftsmanship. I was very impressed. I'll be back!

Excellent merchandise and service. Family business for generations. Gianluca knows everything about the industry. You won't be disappointed.

Thank you, Preziosi. Not just because my wife loves her ring, or because my mother wears that necklace religiously. But because you make it so easy for a guy that knows little about jewelry; because you are so trustworthy; because every friend we've referred to you has come back saying the same thing. It's great to know there are still people that take your profession seriously, actually *helping* clients find a special piece, instead of *selling* customers whatever they can. Thanks again,

I have been using Preziosi for 13 years. I have purchased 3 Tissot watches, which I love. I had them make my wife's engagement ring to match her grandmother's first band. They have made me custom jewelry for my mother in law with her old gold rings and necklaces. I have not been able to find an honest jeweler and have been to many that match the service and stand behind what they make or sell.

If I need batteries replaced they do them while I waite or in an hour. Very friendly, knowledgeable and want the customer to be happy with the purchase. I will be using them for years to come!

Wonderful experience here replacing the battery for my Tissot watch. John showed great professionalism and courtesy - what a gentleman! The actual work was fast - less than 5 minutes and I ended up with a watch with a fresh battery. The shop is mostly about jewelry so I trust the work here done to my watch.

I trust only this place for all my jewelry needs! The second clasp of my vintage sapphire diamond bracelet had broken and I ran to them to get it fixed. Sure enough, in one day, it was done and I was able to confidently wear it out. Of course, I couldn't step into this elegant jewelry enclave without picking up a little Italian jewelry bauble! Beautiful collections.

Preziosi, is the best jewelry store that I have ever done business with and I have purchased and done business with many. They have made me jewelry that I designed and when I picked it up, I got perfection. Also They have some of the most beautiful jewelry I have ever seen and they do perfect repairs. They are high integrity people who sell value and quality.

Their jewelry is unique and most of their pieces are manufactured in Italy by Italy's best. Their prices for what you get is very good. The place is gorgeous, and they are warm, friendly and dependable. I would recommend them one thousand percent, they do not disappoint.

Wow wow wow! I have a ring I never thought could be sized - for 10 years! They did an amazing job! I couldn't see any cut mark. Another ring was sized larger and I couldn't see anything! They are more beautiful than I have ever seen them. The prices were great.

I always try to do business with local, independant, family owned businesses. Well no need to look any further. Great store, very knowledgeable, friendly and helpful owners. Would highly recommend for all of your jewelry needs. The most beautiful handcrafted Italian gold jewelry I have ever seen. GianLuca and Chiara are the best!

After a string of bad experiences with jewelers, I think I've found a professional, honest, and knowledgable jeweler.

What a fantastic place! Everything here is simply gorgeous, and the owners are friendly and welcoming. Preziosi means "precious things" in Italian and they really treat them that way. They made my engagement ring -- a beautiful sapphire and diamond ring with a three-stone basket setting -- and I could not love it more. I took it in recently for cleaning (along with diamond earrings) and now I can't stop looking at it! Preziosi is known for elegant, beautiful jewelry and top-notch service. After you come here once, you'll know that this is the only jewelry store you'll ever need.

The owners of Preziosi really have a lot to do with making this the best jewelry store in the area. It feels like visiting family when we walk in. We are always greeted warmly. They have some of the most beautiful jewelry I have ever seen and they do perfect repairs. I usually let things pile up and walk in with an assortment of "projects" needing attention.

I trust them completely and have no worries leaving my treasures here. There are a number of jewelers in Los Altos but Preziosi is the only one I trust. I tried of few of them and always felt like if I wasn't buying a big ticket item, they didn't want to be bothered. In Preziosi, I feel like they are delighted to see us and will take good care of our jewelry. I highly recommend you stop in and see some really spectacular treasures!

I was seeking a Tissot dealer to change the battery in my T-Touch. It needed a new battery after six years.not bad. I dropped-in here and John was pretty cool. He has a nice little shop with an excellent selection of Tissot watches. Well, John sadly indicated he didn't have the battery even though he usually has it in stock. But, he happily offered to keep my watch and change the battery when he received a new stock.then call me to come pick it up. That's what we did and how it happened. Fast and friendly service. John even re-fitted my T-Touch since it was a little loose. Very good place to visit for Tissots and probably other jewelry too!
