About opal
Opal is made of tiny silica spheres stacked in a regular pattern, and its play of colour comes from light diffracting between them. The size of the spheres decides which colours show. Green and blue come from smaller spheres than red does. A doublet is a thin slice of natural precious opal bonded to a dark backing. The backing makes the slice stronger and deepens its colour, so a doublet can show this kind of brightness at a more accessible price than a solid opal of the same look.

Hardness: 5.5–6.5 on the Mohs scale, softer than most gemstones. Take it off for the gym, gardening or cleaning. Don't soak a doublet or wear it swimming or in the shower, because water can work into the bonded layer over time and cloud it. Wipe it clean with a soft damp cloth.
Birthstone: October
