The peach or orange coloured variety of moonstone is a very versatile stone. Teamed up with black for a dramatic contrast or combined with brass/gold for a more mellow design.
Most people are very familiar with the rainbow moonstone variety. The famous colouring is always popular, but all the other moonstone colours are just as nice. Ghostly grey moonstone, dark or lighter peach and the versatile white variety.
I like using them all together to showcase the broad colour spectrum.
