What doublet means here
A doublet is not a solid opal, and we want that to be clear before you buy. The top layer you see is natural Australian opal, and the dark layer beneath is the backing it is bonded to.
Caring for a doublet
Do not soak this stone in water, because the bond between the layers can weaken. Take it off before swimming, bathing or washing up.
To clean it, wipe it gently with a soft, dry cloth. If you set it in a ring or pendant, a bezel that covers the edge helps protect the join.

About Opal
Opal is hydrated silica made of tiny spheres that split light into flashes of colour, called play-of-colour. Main types include white, black, crystal and fire opal.
- Mineral: Opal (hydrated silica)
- Hardness: 5.5–6.5 on the Mohs scale
- Main sources: Australia, Ethiopia, Mexico, Brazil
- Treatments: Some opal is stabilised or treated to darken its background, and thin opal may be sold as doublets or triplets; ask us about any stone to see its treatment.
- Care: Keep opal away from heat, sudden temperature changes and ultrasonic cleaners, and wipe it with a soft damp cloth rather than soaking it.
