- Cabochon Cut in Jewellery - A cabochon cut is a type of gemstone cutting where the stone is cut and polished in a convex shape with a flat bottom and a domed top, with no facets. This type of cut is typically used for opaque or translucent stones that have natural patterns or inclusions that are best displayed in this type of cut. Examples of stones that are often cut as cabochons include turquoise, opal, and moonstone.
- 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.
