Find Your Perfect Diamond
Made to sit flush against the engagement ring it was designed for.
Every ring is made from start to finish in our Los Angeles atelier.
A second generation jeweler who learned the trade stone by stone, and never stopped looking that closely.
Jim Vernon grew up inside the diamond business. His father founded Frank Vernon Diamond Brokers in 1967, and it was there, on the trading floor rather than at the retail counter, that Jim learned how diamonds are actually judged, bought, and sold among people who handle them every day. He would go on to lead the firm as its President.
A graduate of Stanford Law School, he brought a lawyer's discipline back to the trade: examine every detail before reaching a conclusion. It is the same standard he applies at RockHer today, where no diamond earns his approval until the smallest part of it has.
As Chief Executive Officer, Jim sets the gemological standard for everything RockHer sells, and his long standing relationships across the diamond trade inform how we source, evaluate, and stand behind every stone.
A certificate tells you what a diamond is on paper. Leadership is being certain of everything the paper cannot show.
That conviction shapes how RockHer operates: every diamond independently certified, every stone evaluated by ROSI™, our gemological intelligence built by our gemologists, and every finished ring inspected before it ships from our Los Angeles atelier.
Three decades of membership in the DCWC, a member bourse of the World Federation of Diamond Bourses, including years on its board of directors and service as an officer of the organization.
Served on the board of managers of the American Gem Society Laboratories during the development of its diamond cut evaluation system, an approach to grading light performance still used across the industry today.
Beyond the diamond trade, Jim served as president of the USGA, the governing body of golf in the United States, a role built on the same qualities the trade knows him for: fairness, precision, and stewardship.
The same discipline Jim brings to every stone is available to you before you buy. John Anderson, our Lead Gemologist, reviews diamonds and settings with clients every day.
RockHer is a Los Angeles fine jewelry atelier led by Chief Executive Officer Jim Vernon, a second generation jeweler whose father founded Frank Vernon Diamond Brokers in 1967. Every engagement ring is made to order in our own workshop, every diamond is independently certified by GIA or IGI, and every stone can be evaluated with a ROSI™ Score Report.
