- 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.
- Rose Cut - A flat based cut for a preious stone, leaving the surface covered with triangular facets, usually 24 in total.
It was introduced in the 15th century and popular during the 16th and 17th centuries.
The rose cut was the most popular form of diamond cut until the discovery of the brilliant cut at the end of the 17th century, after which its use declined.
