What Causes Opals to Sparkle?
The sparkle of an opal is caused by a phenomenon known as iridescence. Iridescence occurs when light interacts with the microscopic structures within the opal. These structures, called lamellae, are made up of alternating layers of silica and water. When light strikes the lamellae, it is diffracted, or scattered, in different directions. This scattering of light creates the opal’s characteristic play of colors.
Factors Affecting Opal Sparkle
Several factors can affect the sparkle of an opal. These include:
- Body Color: The body color of an opal refers to the color of the opal when it is not diffracting light. Opals with a dark body color, such as black or blue, tend to sparkle more than opals with a light body color, such as white or clear.
- Transparency: The transparency of an opal refers to how well light can pass through it. Transparent opals, which allow light to pass through them easily, tend to sparkle more than opaque opals, which do not allow light to pass through them.
- Pattern: The pattern of an opal refers to the way the colors are distributed within the opal. Opals with a regular pattern, such as a harlequin pattern, tend to sparkle more than opals with an irregular pattern.
- Cut: The cut of an opal refers to the shape and size of the opal. Opals that are cut into cabochons, which are smooth, rounded stones, tend to sparkle more than opals that are cut into faceted stones, which have flat, polished surfaces.
