Our jewelry is made of Stainless Steel with gold plating. 
Stainless steel is the perfect surface to make gold jewelry that is both affordable and durable as well as allergy free.
Stainless steel makes the gold plating adhere very well and the gold color stays super long. 
At Masté we only use the best plating, which makes the color of your jewelry practically non-fading and thus waterproof.
