Opal’s play of colour is a result of its unique internal structure. Unlike other Gemstones that rely on the reflection and refraction of light, Opals showcase a captivating interplay of colours due to their amorphous silica spheres. These microscopic spheres are orderly in a closely packed, regular grid-like pattern within the Opal. Due to the spacing between the molecules, the light entering the gemstone diffracts white light, scattering all the colours of the spectrum and creating a mesmerizing appeal based on the angle of observation.

The size and arrangement of these silica spheres determine the colours that will be visible. Larger spheres tend towards warmer tones like red and orange, while smaller spheres produce cool shades like blue and green. This scientific marvel of the diffracted light process gives Opals their enchanting and ever-changing play of colour.
