SLIMMS was founded on the belief that acquiring a diamond should feel considered, transparent and personable.

As a private diamond house, we specialize in certified diamond sourcing and bespoke fine jewelery through an education-led approach focused on clarity, strong value and long-term quality.

Because a diamond is never just a purchase. It is something you keep, carry and pass on.

Beyond surface, beyond hype, into the truth.

THE FOUNDER

SLIMMS was founded on one principle: clarity creates better decisions.

Claudia Hofmeister built this house to offer what the industry rarely does, an independent voice that educates before it sells, and advises before she sources. Her approach is not transactional. It is a guided process.

A diamond is never just an object. It is a decision that reflects your values, your taste, and your long-term perspective. Claudia ensures that decision is made from strength — not sentiment, not suggestion, not urgency.

"We don't sell illusion. We guide people back to truth, and to what truly holds worth." — Claudia Hofmeister, Founder

  • "The process was unlike anything I'd experienced buying jewelry. No pressure. Claudia provided complete clarity from the first message to the moment my tennis necklace arrived."

  • "I was referred to Claudia knowing very little. I left knowing exactly what I had, why it was right, and what it was worth. She is very unique and that kind of confidence is rare."

  • "I didn't feel sold to once. Every decision felt like mine."

Every enquiry is handled personally by Claudia.
No forms. No waitlists. No intermediaries.
