Austrian Enamel and Agate Snuff Box

• Agate - Agate is a type of semi-precious gemstone that is made up of silica dioxide, a mineral that is also found in quartz. It is known for its distinctive banded patterns, which are created as layers of silica are deposited in different colours including red, orange, yellow, green, blue, and purple. It is often used in jewellery, decorative objects, and other decorative items, and it is prized for its beauty and durability. Agate is found in many parts of the world, including Brazil, India, and the United States.
• Plique-A-Jour - Plique a jour, which translates from the French as ?glimpse of daylight? is a method of enamelling in which the backing is removed or cut away so the light shines through, with a similar effect to a stained glass window. The enamel is held in place by border.
  
  Although the technique of plique-a-jour has been known and in use since the 6th century, it became popular again in the late 19th century, in Russia and Scandinavia. Plique-a-jour was popular in the Art Nouveau period, especially for jewellery.
  
  Because of the length of time required to produce an item, and the high failure rate, production was limited, and the technique is little used today.
