Handcrafted From Sustainable Materials Every piece in our collection hints at a deeper story and culture. Our partner artisans are located in different parts of Northern India, from the urban New Delhi to various rural, underdeveloped towns around that area. Artisans use numerous techniques to create a wide range of unique styles, such as etching, beading, wire drawing, polishing, electroplating, soldering, carving, braiding, threading and embroidery. Unless otherwise indicated, our jewelry is made with brass components. This ensures that the components are nickel, lead and cadmium-free. Collection: Earrings Sustainable fashion is easy with Matr Boomie. Each pair is sustainably made by hand using traditional techniques in India. Perfect for dressing up, or dressing down, and any look in between. Our earrings use a combination of modern and classic styles for truly a unique design. Choose from gold hoop earrings, disc earrings, teal drop earrings, and countless other styles. Our earrings are primarily made with brass, so they're nickel, cadmium and lead-free. Any silver styles (aside from the sterling silver collections) are made with silver electroplating.
