"The whole experience with Gigi was amazing! My fiancé and I worked with her to design the ring I've always wanted — from the side details to the specifics of the diamond. She even drove out of her way to hand-deliver the ring to us. I'm definitely going to refer her to my friends that are getting engaged! Thanks Gigi ♥"

What Are Lab Grown Diamonds?

Lab grown diamonds are real diamonds — chemically, physically, and optically identical to mined diamonds. Created in controlled environments using advanced technology, they offer the same fire, sparkle, and durability as earth-mined stones, at a fraction of the cost. Every lab grown diamond we carry is certified and graded by independent gemological laboratories.

Why Choose Gems by Gigi?

Most jewelry stores price in the cost of a showroom, a sales team, and retail overhead — you're paying for the building as much as the diamond. Gems by Gigi skips all of that. As a GIA-Trained Expert with 30+ years of experience, I select and verify every stone myself, then sell direct to you — no storefront, no middleman markup layered on top. That difference often means hundreds of dollars in savings, sometimes thousands, on a comparable ring.
