Opal Pendant Set with Five Unset Opals and Triplets

• Nickel Silver - Nickel silver is a metal alloy made from copper, nickel, and zinc. Despite its name, it does not contain any silver. It was developed in the early 19th century in Germany as a less expensive alternative to silver, and it quickly gained popularity as a material for tableware, jewellery, and other decorative objects.
  
  Nickel silver has a similar appearance to silver, with a bright, shiny surface that can be polished to a high lustre. It is also resistant to tarnish and corrosion, making it a durable material for long-lasting items. It is commonly used in the manufacturing of musical instruments such as flutes, saxophones, and clarinets, due to its acoustic properties. It is also used in the production of silverware, jewellery, and watch components, as an affordable alternative to precious metals like silver and gold.
• Doublet and Triplet - A doublet and a triplet are both composite imitation stones, consisting of two or three joined layers. A triplet is made with the crown and base of genuine material, but with a centre layer, usually of glass, the object being to make the stone appear larger than it really is. A doublet consists of only two layers.
  
  Opal doublets are quite common and consist of a thin layer of opal cemented to an opal matrix or black glass.
