'Stormy Waters' Opalized Petrified Wood Necklace - Natural Designer GemstoneThe Stormy Waters Opalized Petrified Wood Necklace is where ancient Earth turns into wearable art. Opalized Petrified Wood began as real wood over 20 million years ago. Instead of turning to stone, it slowly transformed into opal during fossilisation. Ancient wood grain details are still preserved inside the gem. Its glowing blues and earthy flashes come naturally from silica and trace minerals. Most pieces come from prehistoric forests in Indonesia
