Know your stone

Three short notes on what opal is, why ours is light, and how to care for it.

Solid, doublet or triplet?

Solid opal is one piece of natural opal, cut and polished.

A doublet is a thin slice of natural opal joined to a backing.

A triplet is a doublet with a clear cap on top.

All three contain real opal, but they are not worth the same and they are not cared for in the same way. That is why the type is stated on every Lumera stone card.

Why Lumera opal is light

Body tone is graded on a scale from N1, which is black, to N9, which is white. Lumera opal sits at the light end, from N7 to N9: pale blue, with a soft play of colour.

Each stone is judged face up, in daylight. Our settings are polished bright behind the stone, never darkened, so the opal keeps its own colour.

Looking after opal

Do not soak opal jewellery, and remove it before pools and spas.

Keep it away from heat. Do not use ultrasonic or steam cleaners.

Wipe it with a soft cloth and store it in its box.
