Ziegfeld Onyx & Pearl Tassel Necklace by Tiffany & Co

• Onyx - Onyx is a form of agate, used from antiquity and popular again in the 1920s and 30s. European onyx is generally green, but can be many other colours, and can contain bands of black and/or white.
  
  This multicoloured stone is widely used for table tops, lamp bases and in jewellery. Some types of onyx are also used for cameos of which the upper white layer is cut away to reveal the colour beneath.
• Muff Chain - A muff chain is a type of long chain, usually made of a precious metal such as gold or silver, that was worn in the 18th and 19th centuries as a practical accessory to hold a muff, which was a cylinder-shaped cover for the hands that was popular during this time. The chain was worn around the neck with the muff attached to one end, and the other end would be passed through a slit in the side of a coat or jacket, so that the muff could be held close to the body for warmth. Muff chains were often highly decorative and were sometimes embellished with gems or enamel work. While they are no longer commonly used for their original purpose, muff chains can be worn as a vintage accessory or as a decorative element in modern fashion.
• Sterling Silver - Sterling silver is a mixture of 92.5% pure silver and 7.5% of another metal, usually copper. Fine silver is 99.9% pure silver, and is relatively soft and the addition of the very small amount of copper gives the metal enough strength and hardness to be worked into jewellery, decorative and household objects.
