In our atelier we work only with solid gold. Every piece is cast, set and polished by hand, to international goldsmith standards. For you, and for the years to come.
Solid gold
Never plated. Never filled.
Solid gold means the whole piece is gold, with no base metal hidden underneath. What you see on the surface runs all the way through.
Made to last
For the shine. For always.
Unlike plated jewelry, where the gold layer wears thin and discolours, solid gold keeps its colour and shine. It is hypoallergenic and gentle on sensitive skin, and it can be polished back to new years from now.
Your karat
You choose 9K, 14K or 18K. A higher karat means more pure gold and a warmer, deeper colour. Whichever you choose, it is solid gold throughout.

Gorgeous ring!
So incredibly happy with my breast milk jewelry. It was more than worth the wait. A lasting memory forever of the period in which I pumped full-time for weeks for our baby who was born prematurely. Thank you all! 🤎

Gorgeous memory
What an incredibly beautiful and elegant ring. After sending in my milk I stopped breastfeeding, so it has a beautiful and emotional value. I wear it with pride! More than worth the wait.

Solid gold
Made to last a lifetime
We never work with gold-plated jewelry. Our gold pieces are made from solid 9, 14 or 18 karat gold — yellow, white or rose gold.
A timeless material for a memory you can wear every day, cherish for years and perhaps one day pass on.
