18k gold plated brass hook with brass and jasper. All jewelry is handcrafted at a 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. 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.
