Jewelry designer Michele Mercado's showroom and work space in Boston's historic South End is filled with metal treasures. Her award winning designs feature 100% recycled Harmony Metals and she is a big champion of up cycling clients old pieces into new designs that will fit with their lifestyle. The timeless styles are minimal, clean and modern. Also on display is a unique grouping of handcrafted pieces of fellow jewelry artists. During my visit the hammered wall compositions of clouage artist Robert Kobayashi were incredibly detailed and meticulously constructed out of old metal.
