- Onyx - Onyx is a form of agate, used from antiquity and popular again in the 1920s and 30s. European onyx is generally green, but can be many other colours, and can contain bands of black and/or white.
This multicoloured stone is widely used for table tops, lamp bases and in jewellery. Some types of onyx are also used for cameos of which the upper white layer is cut away to reveal the colour beneath.
- Hardstone - Hardstone is not a scientific name for a particular gemstone, but a word used to describe any one or more semi-precious stones used in jewellery and decorative arts, and can include jade, agate, onyx, rock crystal, amber, jet and carnelian. Softer stones and minerals such as soapstone, and alabaster and hard stones used in building such as marble or granite are generally excluded.
