Made for her. Made for you.
Made to order in Los Angeles, since 1967.
Upload a few photos of her. Our AI finds the ring she would choose.
Not ring photos. Just her. ROSI reads the jewelry she already wears, whether she lives in warm or cool metal, and the shapes she leans toward, then matches her against our live inventory of certified natural diamonds and settings. Her ring, and the reasoning behind it, in your inbox in about a minute.
The ring it names is not an idea. We hold the certified diamond inventory and run our own Los Angeles atelier, so it ships in 8 to 12 business days at one fair price.

Metal, scale and shape, each read tied to the photo it came from.

Her reading and her rings, with anything her photos did not settle.
RockHer™ is a Los Angeles-based engagement ring designer specializing in custom engagement rings, natural diamond engagement rings, and lab grown diamond rings. Every ring is made to order in our private atelier. Whether you choose a natural or lab-grown center diamond, our gemologists guide every decision with the same care they'd offer a close friend.
A gemologist's workbench in Los Angeles, 1967. No storefront. No catalog. Just a reputation built one diamond at a time.
When friends needed to buy a diamond, they came to us — not a store. Jim Vernon spent five decades as a trusted gemologist, advising clients the way a doctor advises on health: honestly, carefully, and without a sales agenda.
RockHer was built to give everyone that same access. Every ring carries that original promise — uncompromised quality, radical transparency, and craftsmanship that exists only once.
Every ring is made entirely to order. No inventory. No warehouse. No compromises.
"We only work in solid gold. We only set natural accent diamonds. We only make to order."
Our gemologists will tell you exactly what each option means for your ring,
your diamond, & your decision. No judgment. Just clarity.
Billions of years in the making. GIA certified. Each diamond carries a geological history that makes it irreplaceable. The traditional choice for those who value rarity and long-term significance.
Chemically, physically, and optically identical to mined diamonds. IGI certified. Ethically created in controlled environments. An exceptional option for those who want to maximize quality and carat weight.
Built by GIA gemologists. Available wherever you reach us. Connected to every system. Confirmed by human hands before any diamond ships.
ROSI™ began as the scoring rubric Jim Vernon used at his bench — a way to answer the question every friend kept asking him: what’s the best diamond for my money? Two years and 50,000+ diamonds later, that judgment scaled. ROSI now runs on every channel a customer might use to reach RockHer™ — chat, phone, email, SMS, Instagram, Facebook — with live access to inventory, pricing, and order data.
And before any diamond ships, our gemologist still examines it personally. ROSI does the curation at scale; the gemologist confirms in person.
