Silicon dioxide in a crystalline form is quartz. The tube or eye agate, referring to the unique patterning of this semi precious quartz, which is also formed as a banded chalcedony, is naturally created in nature, chalcedony consisting of twisted crystal fibres which delight in there colour and numerous varied forms. The composition of these forms of agates is complex and leads to the many and varied types which are found all around the world.

Agates are formed by volcanic action, agates develop in gaseous cavities within lava and may also be found as replacement mineral in sedimentary rock layers and clay stones. The Romans coveted agates and they are mentioned in text of the ancients. Agates have been discovered in use as adornments as long ago as seven thousand years and have been collected in modern times with intent by the victorians since around the turn of the nineteenth and twentieth century.

The beauty of agates is obvious and is exhibited in the variety of colours, multitude of banding and other forms within the banded and varigated agates which have recently been created into our range of finely polished freeform bowls. Freeform relates to the artisans use of the free flowing undulations of the raw agate material. Allowing nature to determine the shape and outcome of the finished object. The quality of the semi precious agate from Madagascar is exceptional. Our tactile range of superb agate bowls will delight and intrigue on sight.
