A stunning aurora Opal set in sterling silver. Beautiful colours change in the light, purple, blues, greens, orange and pinks. 
18” chain. 
This type of resin based synthetic opal is a playful alternative to natural opal. Its swirly patterns allow it to show different colours from all angles, making each cut cabochon truly unique.
It has a hardness of 4 on the MOHS scale. The opal is hand cut and polished. 
Handmade in my Suffolk workshop.
