- 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. - Amber - More frequently used to refer to the colour, than the material from which the word is derived, amber is the fossilized resin from ancient forests. It is not produced from tree sap, but rather from plant resin. The resin is aromatic, and can drip from and ooze down trees. In colour, it may be a deep honey colour, (amber), brown, or white. As it oozes out it fills internal fissures in the tree, trapping debris such as seeds, leaves, feathers and insects. The debris trapped within the amber can assist in dating the deposit.
In its natural state it is found in rocks, on the sea floor (from where it may be washed up to the shore) and mined, using both open cut and underground techniques. About 90% of the world's amber comes from Russia. Amber has recently been discovered at Cape York in Northern Australia
Amber is often incorporated in jewellery, and used in pipe stems. The shine on the surface of amber becomes even more intense when it is worn and used regularly. Genuine amber, when rubbed, will release a slightly musky scent. - Coral - Coral used in jewellery. Coral is a material that is commonly used in jewellery making. It is made up of the skeletons of tiny marine animals called coral polyps. There are many species of coral, but only one group, Corallium, is suitable for carving, and thus can be used in jewellery manufacture. These have a deep red or pink orange skeleton and are known as "noble coral" or "precious coral".
