Aleksandra Vali’s Modern Art Jewelry: The Infinity Ring is made from Sterling Silver with a Fresh Water Pearl. One side has deep texture and the other side has a smooth surface. Ring sizes are adjustable.
Before the oxidisation is carefully polished back to reveal the silver underneath, the surface of the Anthracite Ring by Alicia Hannah Naomi is matte black and chalky. Due to the very nature of any surface treatment, it would not last long in this.
