ETHIOPIAN OPAL PENDANT
An amazing Ethiopian Opal Pendant. A rainbow of colours flash around this gemstone including red, green, blue and orange. This Opal not only has the range of colours but it is also translucent, a quality that gives this gem an otherwordly feel. My photos do not do this stone justice, it is so much better in person. A beautiful addition to your jewellery collection or a great gift for a lucky friend. This pendant comes with a black cord necklace and in a pouch.
Opal 1.3cm x 1cm, whole pendant 2cm, 1.97g
Opal: SiO2 · nH2O
Hydrated Silicon Dioxide.
The chemistry of Opal is primarily SiO2 and varying amounts of water. The amount of water varies from 5 -10% and greater. This water can help geologists determine the temperature of the host rock at the time the opal formed. Recent finds in Ethiopia have unearthed world class Opals with beautiful translucence and play of colour.
