A beautiful full color playing natural precious opal from Ethiopia that has been exposed to smoke to create this dark gorgeous version.

It has beautiful iridescent reflections, difficult to capture in all its beauty, it is small, it is very expressive. Ideal for silver and gold. Uncalibrated pair, cabochons 5mm. Can't drill!

Expensive opal is a stone for every magpie, it brings playfulness and coquetry to life and necessary nobility, but in an enlightened form.

Caution applies to it as it does to all natural expensive opals: do not bathe with it! may (but may not) lose or change opalescence. Normal humidity, rain won't do anything to it, it only bothers it when it gets completely wet. (sea, pool, bathtub, washing dishes ..)
