18" necklace with black agate, plated hematite, and brass. 2 inch extender. All pieces are made to order and handcrafted at our studio in New Jersey by skilled artisans who share our passion for quality and originality. Each piece is unique so stones and glass may vary in shape, size, and color. Stone inclusions may be visible to the eye and are considered a part of their beauty. Please allow 2-5 weeks for production. Our jewelry consists of plated metal, which may darken or tarnish over time with normal wear. Gently wipe the metal surface with a soft cloth to clean, however, excessive polishing may rub off or scratch the plating. Avoid direct contact with lotions, perfumes, or oils. Excessive light, heat, or moisture will deteriorate the quality of glass, plating, and stones. Do not wear jewelry while in a pool, hot tub, or bathing. If treated with care, your jewelry will last for years to come.
