What is Crushed Opal?

Crushed Opal is a diverse inlay material that is commonly used for jewelry making and craft projects. 

The Material & Benefits

Most commonly, Crushed Opal is a Lab Created material. Lab Created Opal is grown in a controlled environment that is formulated to replicate the natural formation of Genuine Opal.

Our Crushed Opal is a blend of 80% silica & 20% resin and is resistant to chemicals such as acetone and alcohol. By using a polymer it also creates a slightly softer product making it superior for turning and cabbing. This provides a better user experience, as you will experience less cracking and crazing compared to Natural Opals. 

The first form is a large slab of synthetic opal that is then crushed down into small granular pieces. We offer a range of grain types, so you can find the size that works best for your needs.

The material is made in hundreds of color combinations providing endless possibilities for creative minds who value working with their hands.

A: Each color of Crushed Opal can be seen differently depending on the lighting, angle and the way the material is being used.
