  • 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.
  • Emeralds - Emeralds have been used in jewellery making for thousands of years, and are prized for their deep green colour, which is caused by the presence of chromium and vanadium in the mineral beryl. Because of their rare colour, emeralds are often more valuable than diamonds of a similar size and quality. In jewellery making, emeralds are typically cut into round or oval shapes to maximize their color and clarity. They are often set in gold or platinum and used as the centrepiece of a piece of jewellery, such as a ring or necklace. They can also be used in combination with other gems, such as diamonds, to create intricate and beautiful designs.
