18 carat gold plated brass hooks with green onyx. 2.75 inches. Perfect gift for Mother's Day, birthdays or graduations. Natural stone varies in color, veining and shape from piece to piece and no two pieces will be exactly alike. Actual color variations for each piece may vary from sample photo. 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. 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.
