'Force of the Ocean' Opalized Petrified Wood Necklace - Natural Designer GemstoneThis piece of jewellery is undeniably stunning! Opalized Petrified Wood is a remarkable geological occurrence where the wood's original framework is replaced by opal, a hydrated silica mineral. Known as "wood opal," this material preserves the wood's organic structure through a process akin to typical petrification, but with unique colour variations, including blue hues. The opal fills the wood cells, maintaining its distinctive grain and patterns.
