History: Boulder opals, as the name suggests, are mined from large ironstone boulders under the ground. Thin veins of colourful opal forms in cracks and fissures in these boulders. Because these veins of colour are so thin, opal cutters need to leave the ironstone on the back of the opal to form a full sized stone.

The earliest diamonds were found in India in 4th century BC, although the youngest of these deposits were formed 900 million years ago. A majority of these early stones were transported along the network of trade routes that connected India and China, commonly known as the Silk Road.

Gold was generally used for a couple thousand years solely to create things such as jewelry and idols for worship. This was until around 1500 BC when the ancient empire of Egypt, which benefited greatly from its gold-bearing region, Nubia, made gold the first official medium of exchange for international trade.
