With over 100 years of family experience designing and producing fine jewelry in San Francisco, we are a full service shop specializing in custom engagement rings and timeless family heirlooms.

Custom Jewelry 

Engagement Rings 

How many people can say they got their ring from the same shop that their great grandparents did?  Cresalia's proudly designs and manufactures engagement rings for over three generations of families in San Francisco with proven value and consistency.  We work in gold and platinum and maintain a rare selection of stones including diamonds, rubies, sapphires, emeralds, tanzanites, and many more. 

Family Heirlooms & Heirloom Redesign

Cresalia's understands the multigenerational value in jewelry more than anyone else, whether it be custom designing a bangle bracelet with your children's birthstones, or taking a  family heirloom and remolding it into a functional, modern design.

Instead of letting heirloom jewelry fall to the bottom of your jewelry box, take your pieces to Cresalia's to have them made over. There is a plethora of ways to breath new life into old jewelry by modernizing an old setting or creating a whole new one.

Our trained jewelers are able to restore defective or old jewelry. Whether your jewelry needs to be polished or needs a new asset, our work will make your old jewelry look brand new!
