Discover World Record Gemstones

KAT FLORENCE

Kat Florence is an internationally recognized fine jewelry house specializing in ultra-rare natural gemstones and bespoke high jewelry design. Founded by Kat Florence, the brand is known for sourcing and working with some of the world’s rarest stones, including D-Flawless diamonds, Paraiba tourmalines, Golconda diamonds, and other exceptional collector-grade gems.

Each Kat Florence jewel is individually designed and handcrafted, often as a one-of-a-kind piece. Designs are created with a focus on longevity, craftsmanship, and heirloom quality rather than trend-based fashion. Many pieces are built around singular gemstones that exist only once in the world.

Kat Florence jewelry emphasizes ethical sourcing, expert cutting, and meticulous setting, with a commitment to preserving the natural integrity and value of each gemstone. The brand’s work is frequently associated with legacy collecting, private commissions, and museum-quality jewels intended to be worn and passed down.

Kat Florence is not a mass-market jewelry brand. It operates as a high-jewelry atelier focused on rarity, permanence, and enduring value.
