Why Corona couples choose Franzia
A bench-built ring from a GIA-certified stone you can hold before you commit.

If you are shopping for custom engagement rings Corona CA, Franzia Diamonds is the family-run counter inside Superior Grocers, Corona, CA — the same shop you walk past on a grocery run becomes the place you sit down with a jeweler, a GIA grading report, and an honest conversation about the ring you are actually building.
Every custom ring starts the same way: a quiet bench consult where we listen for what the wearer actually lives in — work, gym, kitchen — and work backwards from there into stone, mounting, and metal. We pick the diamond first (a GIA-graded stone, no report no slot on the case) and then fit the setting to the stone, not the other way around.
Stones come from independent suppliers we trust — every one ships with its GIA lab report, and the report travels with the stone from the supplier bench into your hand. Because we buy individual stones for cut quality and clarity, not from a parcel, our pricing tends to land outlet-range on stones you would otherwise pay retail for at a chain. The savings pass straight through to the counter; the grading stays at the lab.
The build itself — CAD review, mounting choice, final setting, and inspection under the loupe — happens at the Franzia Diamonds counter inside Superior Grocers, Corona, CA, in front of you. Most custom rings are ready in a few weeks. Come see the case in person during store hours; for a custom-build consultation, reach the counter ahead of time and we will hold the bench open.
