Facetted Carnelian Necklace with Gilded Clasp

• Faceting - Faceting is a technique of removing material from a curved surface, to give a series of flat surfaces but retaining the profile of the original surface.
  
  The technique is most commonly associated with diamond cutting where the various cuts used such as rose cut and brilliant cut, add life and sparkle to the stone, whilst at the same time removing as little of the stone as possible.
  
  Faceting by grinding is also used to decorate glass. The stems of many drinking glasses are decorated by cutting a series of flat surfaces on a circular stem, and hollow vessels such as vases may have faceted surfaces.
  
  In furniture faceting is often applied to legs of tables and chairs, where a circular baluster shaped section is flattened so as to form an octagonal section.
• Gilding - Gilding is a method of ornamentation whereby a thin sheet of gold metal is applied to items made of wood, leather, ceramics, glass and silver for decorative purposes.
  
  For furniture including mirrors, the sheet of gold is usually applied over a coating of gesso. Gesso is a mixture of plaster of Paris and gypsum mixed with water and then applied to the carved wooden frames of mirrors and picture frames as a base for applying the gold leaf. After numerous coats of gesso have been applied, allowed to dry and then sanded a coat of "bole", a usually red coloured mixture of clay and glue is brushed on and allowed to dry, after which the gold leaf is applied. Over time parts of the gilding will rub off so the base colour can be seen. In water gilding, this was generally a blue colour, while in oil gilding, the under layer was often yellow. In Victorian times, gilders frequently used red as a pigment beneath the gold leaf.
  
  Metal was often gilded by a process known as fire gilding. Gold mixed with mercury was applied and heated, causing the mercury to evaporate, the long-term effect of which was to kill or disable the craftsman or woman from mercury poisoning. The pursuit of beauty has claimed many victims, not the least of which were the artists who made those pieces so highly sought after today.
• Carnelian Glass - Carnelian glass is a type of glass that is colored red, orange, or brownish-red. It is made by adding iron oxide to the glass mixture. The color of carnelian glass can vary depending on the amount of iron oxide that is added, as well as the firing temperature. Carnelian glass is often used to make beads, jewellery, and other decorative items. It can also be used to make stained glass windows and other art objects. Carnelian glass is sometimes called "carnelian chalcedony" or "carnelian quartz."
  
  Carnelian glass was first made in the Roman Empire. It was also made in ancient Egypt, Greece, and Mesopotamia. Carnelian glass was not made again until the Renaissance, when it became popular again. Today, carnelian glass is made in many countries around the world.
