Early access · shopper pre-launch
Be first to shop lab-grown, GIA-certified engagement rings.
Franzia Diamonds is opening shopper early access to our lab-grown collection — every stone graded by GIA, every stone available to hold under our loupe at the Family-Run Counter inside Superior Grocers, Corona, CA. Join the list and we'll send you the first invitations to appointments, custom builds, and limited drops before they open to everyone else.
Why join the list
Lab-grown, GIA-certified, viewable in person — before anyone else.
Shopper early access means you get the first look at each lab-grown drop, the first custom-bench slot, and the chance to hold a graded stone at the counter before walk-ins do.
Lab-grown · GIA-certified
Every lab-grown stone on our counter ships with its GIA grading report — every 4C verified, not promised.
In person, before you decide
See stones under our loupe at the Franzia Diamonds counter inside Superior Grocers, Corona, CA — not just on a screen.
First-look invitations
Members get early access to limited drops, custom-bench builds, and appointment slots before they open publicly.
Join the shopper waitlist
Drop your email. We'll send the first invitation.
No newsletter dump, no spam — just a real note from the counter when there is something worth seeing: a new lab-grown drop, a custom-bench slot, or a one-on-one appointment before walk-in opens for the day.
- A short note from someone at the counter, not a marketing blast
- First access to lab-grown drops the day they go on the case
- Direct line to a private appointment at Superior Grocers, Corona, CA
