I selected this pair of opals to work with because of their amazing bright blue . There is only one pair exactly like these. 

Wearable art from nature. This is a very rare pair of earrings as they're made from 20 million year old petrified wood from Indonesia. The wood has opalized to create this magnificent gemstone specimen. This feels like gemstones feel, not like wood. 

I have placed them on sterling silver wiring and with paraiba blue opals. As shown on French Ball earwires. The earwires are sterling silver. The hoops are silver alloy. These are about 2 5/8”, Please choose your earwire preference. 

How was this formed?

Indonesia is a volcanic island chain that is currently active and this volcanic activity produces a wide array of unusual minerals and rocks. When wood is buried by volcanic ash and silica is mobilized from the ash, the silica will penetrate into the wood and replace the grains of the wood. Opal is a hydrated silica.

This is a one of a kind piece and a rare material. 

Your earrings will arrive beautifully giftboxed.
