Master the art of gouache jewelry design with world-renowned experts
“In a world of digital art, mastering the timeless beauty of gouache illustration is a mark of true luxury — and your key to standing out with elegance.”
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 the art of the gouache so you can transform your designs into true treasures.
Learn the Timeless Art of Jewelry Gouaché
What Is a Gouache Rendering (Also Called a Gouaché in France)?
A gouaché is a hand-painted, life-size jewelry rendering using gouache—an opaque watercolor that brings brilliance, depth, and realism to your designs.
What Is It Used For?
More than a drawing, a gouaché is a powerful tool.
– A dreamlike preview for clients: It helps them visualize their piece before production, sparking emotion and desire.
– A technical drawing for artisans : It guides the workshop with precision, ensuring faithful execution of the design.
– A precious archive for Maisons: It documents the creative heritage of each brand, preserving every unique model.
– A collectible artwork in its own right: Today, gouachés are sought-after by collectors for their beauty and rarity.
Why Choose Gouache Over Digital Rendering?

In a world of AI and 3D renders, gouaché sets you apart.
It’s not just a skill—it’s a statement.
A hand-painted gouaché tells a story of craftsmanship, emotion, and time.
It transforms your designs into true artworks that captivate clients and elevate your brand.
Unlike digital tools, gouaché brings warmth, poetry, and timeless beauty— a rare, human touch that clients instantly connect with.

I can recommend The Art of the Gouache course! Up until a year ago I didn't know how to paint, now I own my own business. It's great to learn to paint with Jeanne & Helene.

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!
