Gemstone Tumbled Stone Pendant Made of Opalized Wood – Natural, Characterful & Hand-Picked

This exceptional pendant is made from opalized wood, a fossil material created by natural mineralization over millions of years. Original wood structures were gradually replaced by silicon dioxide – a rare and fascinating combination of organic origin and mineral refinement.

The tumbled stone displays a warm, earthy color palette with fine markings and a polished surface. Each piece has its own unique grain, making this pendant an absolute natural one-of-a-kind.

The pendant comes from Indonesia, one of the most renowned discovery sites for high-quality opalized wood with particularly clearly preserved structure.

With its size of approx. 40 × 20 mm, it is pleasantly present without appearing heavy. The 2.5 mm drill hole is suitable for various types of chains – leather cord, omega necklace, or delicate silver chain. The included black fabric cord (approx. 80 cm) is soft, flexible, and ensures high wearing comfort.
