Redefining goldsmithing

About Charlotte de Koomen Jewelry

We’re creating something new—more than a goldsmith, more than a jewelry brand. By merging expert craftsmanship with our iconic CdK designs, we bring you the perfect blend of tradition and innovation.

Dutch design_ handcrafted in Amsterdam

From design to creation, we do everything in-house. Our jewelry is designed by Charlotte de Koomen. The CdK collection and our custom orders are handcrafted by our team of experienced goldsmiths in our atelier in de Pijp, Amsterdam.

Premium materials

We work with 14, 18 and 22 karat recycled gold and real gemstones. Most used gemstones are diamonds, tourmalines, sapphires and pearls. If you want to use your own gold or gemstone in your jewel, please reach out to us to hear about the options.

Appointments

For jewelry for special occasions or unique designs, we recommend booking an appointment. This ensures we have dedicated time to focus on creating your personalized piece.

Open atelier & store

We have an open atelier & store. Come check out our atelier and jewelry collection any time you like! No appointment required.

Goldsmiths

We have a team of amazing goldsmiths with decades of experience. Our goldsmiths have been taught at the Vakschool Schoonhoven, the only official education for the professions of goldsmith, jeweler and watchmaker in The Netherlands.

Founders

CdK was founded by sisters Charlotte and Rozemarijn, who grew up in a goldsmithing family. They form the perfect duo: Charlotte drives the creative vision, while Rozemarijn leads the business side of the company.
