The plug of the earring has a pink topaz of 3.5 mm. Inspiration: The collection is inspired by the Zeeland button ring, which my mother used to give me. This ring from Zeeland formed the basis for a collection of jewelry made of porcelain, silver, red coral and pearls. The Zeeland knot jewelry is all handmade by myself from my studio. Of course I also make these jewelry in gold on request. Even if you still have a Zeeland button of jewelry or a blood coral bracelet or necklace in your closet that you don't use, I'm happy to make something beautiful out of it! Handmade and packaged with love!
