General Info
Location: 94 South Washington St. in Sonora, Ca in the downtown historical area in the middle of the California gold country. At Sonora Jewelry, we can service all of your jewelry needs. We do everything on site. We can repair or restore your broken or worn down jewelry. We have a varied inventory of ready made retail items, insuring you will find that special unique piece for anyone on your gift list. We also custom make jewelry for you. Many of our ustomers bring in their jewelry that they have not enjoyed for years and have the gold and diamonds turned into the pieces that they can enjoy. Others have us supply the stones. We only use clean gold and we work hard to give you the most value from your old jewelry to make this as affordable for our customers as possible. The design is $100 and we apply that to your actual created product. How can you lose? This is a family owned company, passed down to Louis Mastro from his father and his grandfather being jewelers for 4 generations. The Mastro family has worked for many of the top fine Jewelry manufactures and designers in the jewelry industry for over 100 years and in that time, experience and talent has been passed down from one generation to the next. With access to computers and new technologies in the last 20 years designing jewelry has become a precision art. With computer aided design you see the jewelry design in the exact 3D view that will be created. No more guess work. We have been doing cad designs for the last 10 years using several jewelry design software programs and creating the ability to design in unlimited designing techniques.

We have had nothing but wonderful expierences from Sonora Jewelry. Louis and his wife are amazing! Even though we live out state, we refuse to shop anywhere else.

My experience with Sonora Jewelry was nothing but fantastic. My fiancé proposed to me the first week in December in Oregon, right before we traveled to Murphys, CA to visit his family for the holidays. The ring he gave me was his great-grandmother's and was two sizes too small for me. Since he proposed only a few days before coming to California for the holidays we did not have enough time to get it sized in Oregon. When we arrived to Murphys, his mother told us we should try Sonora Jewelry Design because she had previous good experiences with them. When we took the ring into them, it was four days before Christmas and we were almost positive we would not be able to get my ring resized until after the holidays since so many people get engaged right before and on Christmas. When we first walked into Sonora Jewelry Design they told us it would not be until after the first week in January before they could get to resizing my ring. However, once we told them our situation and they saw my ring, the two employees, Natalie and Rod, said they would try their hardest to get Lewis, the jeweler, to resize my ring before Christmas. I left my ring at the shop and the very next morning I received a call from Lewis saying he would have it resized by that afternoon. The day after I left the ring with them. I could not have asked for a better experience and would recommend Sonora Jewelry Design to anyone!

Louis and Natalie are awesomely friendly. You will not go wrong having Louis design or work on your precious jewelry. You would be hard pressed to find anyone better.
