Third-Floor Jewelry Repair Shop by Union Square: Cresalia

Most people walking down Sutter Street have no idea that one of the city's oldest jewelry families works three floors above them. Cresalia Jewelers, at 266 Sutter St on the third floor, sits a block from the Sutter-Stockton Garage at the edge of Union Square and the Financial District. It is a full-service jeweler with a repair bench, a resident gemologist and a case of vintage engagement rings, and it is the kind of place you bring the piece you are nervous about handing to a mall kiosk.

The family's history in the city runs long. According to the shop's About page, the Cresalia family arrived in California during the Gold Rush in the mid-1800s and has been part of San Francisco business life for more than six generations. The services page adds that the family brings over 100 years of experience designing and producing fine jewelry here. When you walk in or call, the site says, you will be greeted by that same family, and the shop proudly notes that it has made engagement rings for three generations of the same households.

That depth shows in the stock. The current showcase leans heavily on estate and vintage pieces: an Edwardian platinum diamond ring from around 1910 with hand engraving, a 1920s Art Deco ring with an inscription inside the band, and 1940s engagement rings with illusion settings. Many listings note complimentary resizing, and several say the ring can be carefully resized upon request. That care for old settings is exactly what you want when the piece on your finger came from a grandparent.

The repair section of the services page is brief but broad. The shop specializes in repairs on rings, earrings, bracelets, necklaces, watches and silver pieces, and says the work is done promptly at competitive prices. Silver is worth highlighting: plenty of jewelers decline hollowware, flatware or heavy silver pieces, while Cresalia names silver alongside fine jewelry. The site also says its trained jewelers are adept at restoring defective or old jewelry, from a simple polish to rebuilding what has worn away.

Pearls deserve a mention too. The current showcase includes a vintage double-strand Akoya pearl bracelet with an amethyst clasp and a pearl necklace in the form of two perched birds, which tells you the shop handles pearl work regularly. If an inherited strand has gone loose or the clasp no longer closes securely, ask about it during your visit. A strand that is restrung and knotted between each pearl will hang properly again, and the knots keep pearls from scattering if the thread ever breaks.

Jay Cresalia is a certified gemologist, and the shop offers appraisals for insurance and estate purposes as well as consultations on diamonds and colored stones for buyers and sellers. It also buys or brokers diamond and gemstone jewelry. If you have just inherited a box of jewelry and do not know what is real, combining a repair visit with an appraisal makes sense: the gemologist can tell you which pieces are worth restoring before you spend anything on them.

The location page invites you to drop in during business hours to browse, start a custom piece or ask about appraisals and repairs. It lists Tuesday to Thursday from 10 am to 5:30 pm, Friday from 10 am to 3 pm, Saturdays by appointment, and Sunday and Monday closed. Because Friday is short, plan anything involved for earlier in the week. The services page also has a Schedule a Repair button, which is the easier route if you want a Saturday slot or time with the gemologist.

Since the showroom is upstairs in an office building rather than on the sidewalk, it stays quiet even on busy shopping days. Take the elevator to the third floor. Bring the piece itself plus any paperwork or past appraisals you have, especially for older diamonds, since a previous report helps the gemologist compare condition over time. If the piece is going to be resized, wear it for a day beforehand and note whether it feels tight in the evening or loose in the morning. Fingers change through the day and with the weather, and that note helps the jeweler pick the right size the first time.

Step outside and you are in one of the best blocks downtown for architecture. Half a block east on Sutter, the Hallidie Building, designed by Willis Polk and finished in 1918, has one of the earliest glass curtain walls in the world, with ornate blue and gold cast iron framing the glass. A few minutes north on Grant Avenue, the Dragon Gate at Bush Street marks the entrance to Chinatown. Union Square itself is two blocks west, with its palm trees and the Dewey Monument at the center.

The shop's own directions are the easiest: one block from the Sutter-Stockton Garage and two blocks from Montgomery Street BART. Several Muni lines cross the area, and the Powell Street cable cars run a few blocks west if you want to make the trip a little more scenic.
