Raw Cornish Turquoise and Gold necklace. 

Collected from Gun Heath China Clay Pit. 

Very special piece.

Cornish Turquoise is usually composed of feldspar, quartz and micas depending on where it forms and the different minerals oxidising, more copper will make it blue, more iron will make it more verdant. I love the dusty milky opaque blue hue of the Kernow variation. You can actually find it a stones throw from where I grew up, outside St Austell, Cornwall, where kaolinite (China Clay) is still mined. Turquoise was a happy accident when mining for kaolinite, so although its discovery was a by product of the huge China Clay Industry, it obviously unearthed some treasure.

Made with Gold filled 18 K chain and findings. Gold filled is much more durable than plated, and with care should last just as long as pure gold (not that anything is pure gold, gold is a soft metal that has other metal added to it otherwise it would break). 

Necklace is 18 inches long.

See photo of me wearing a similar necklace for idea of length / scale.
