Master the art of gouache jewelry design with world-renowned experts

“In a world of digital art, staying true to the timeless beauty of gouache illustration is a mark of luxury, because it’s a matter of time, emotion and authenticity.”

Hélène & Jeanne KARPOV

Hello, we are Jeanne and Hélène Karpov, high-end jewelry designers and gouachers.

After spending 20 years working at prestigious and exclusive houses on the Place Vendôme in Paris, we’ve decided to teach YOU everything we know about our professions.

Gouache rendering:
the timeless art that brings jewelry to life

Do you know what is gouache? Technically speaking, it is the art of rendering using opaque watercolor.

Mastery of this delicate craft is rare, with only a handful of experts worldwide recognized as true masters of gouache—and we are honored (and happy!) to be among them. Over the past 20 years, we have honed our skills working with some of the most iconic luxury brands from the LVMH, Richemont, and Kering groups, as well as many others. What we are about to share with you is the culmination of decades of work, passion, and dedication to this ‘savoir-faire’.

Moreover, some of the techniques we teach are entirely unique—self-discovered and refined through years of experimentation and innovation. These are methods you won’t find anywhere else, designed to help you master the art of jewelry gouache with unparalleled efficiency.

Why choose gouache over digital rendering?

Gouache is more than a technique—it’s an experience. Whether you practice it for fun, relaxation, or to create stunning illustrations for your home, this art form brings beauty and tranquility to your life.

For aspiring designers, mastering gouache is more than just an asset—it’s a way to stand out. In a world where digital rendering is becoming increasingly dominant, mastering this traditional technique positions you as a designer who is detail-oriented and passionate about high-quality work. It sends a clear message to customers and employers: your creations are not merely sketches—they are true works of art, crafted with care and dedication.

Even without perfect mastery, a gouache rendering captivates clients with its charm and elegance—something a digital or 3D rendering simply cannot replicate. Many customers appreciate the handcrafted, timeless quality that gouache brings to the design process.

Discover the timeless art of gouache and elevate your creativity to the next level.

  • I thoroughly enjoyed the Opal course. It was great to deep dive into specifics: colours, opals elements, types of opals. Having the reference really helped and also the close up footage and step by step. With these tools, I am now able to apply them to my own opal collection. Merci!
