Play of Colour 
Opal’s have a fascinating and unique optical feature called ‘play of colour’. Play of colour occurs because opal is made up of sub-microscopic spheres stacked in a grid-like pattern. This structure breaks up light into spectral colours and the colour you see depends on the size of the sphere. 
Opal is the only gemstone to display this fantastic phenomenon.
 
Care and Cleaning
Opal can be a delicate gemstone so we do not recommend that any opal jewellery be worn everyday. Opal’s can be scratched by other gemstones and metals so if you keep your jewellery in a jewellery box, make sure your opal jewellery in a stepparent compartment. 
Opal is a relatively stable gemstone, meaning it is not often effected by light, heat or chemicals but we would advice removing any opal jewellery before doing anything that may bring it into contact with intense heat or any chemicals. 
Opals should not be steam or ultrasonic cleaned and harsh jewellery baths should not be used due to waxing, oiling and dying treatments that are sometimes used on opals. To clean your opal jewellery at home we recommend a jewellery or gem cleaning cloth or warm water and a soft brush.
