Colourful Dyed Agate
Agates are fascinating stones. They occur with wonderful distinctive concentric patterns and bright colours. Natural brightly coloured agate is not nearly as common as plain white or colourless agate, so due to its porous nature, it is often dyed to produce richer, more vibrant colours. This artificial “enhancing” can yield bright greens, blues, pinks, yellow – virtually any colour you can think of.
Mineral treatments of natural stone goes way back to centuries past and although agate occurs globally, the modern process of dying agates began in Germany in 1854. The dying process first involves boiling the stone in a strong bicarbonate solution, and then soaking it in a chemical solution. The type of chemical solution depends on the colour you want to achieve, for example to produce red, you would soak the agate in an iron nitrate solution. Below are some examples of gorgeous handmade jewellery, available from Big Skies Jewellery, which show you the wonderful variety of colours of beautiful dyed agate.
