Boulder Opal Pendant – with Fabric Cord

A natural Boulder Opal pendant that captivates with its fascinating play of colors and warm, organic matrix. The finely polished stone displays the characteristic opal reflections – vibrant blue, green, or rainbow shimmers – that change vividly depending on the light.
The brown ironstone matrix lends depth and earthiness to the opal, making each piece a unique natural work of art full of expressiveness.

Measuring approx. 25 × 14 mm, this pendant is slim, elegant, and ideal for daily wear or special occasions.
The 2.5 mm drill hole is perfectly suited for leather cords, delicate silver chains, or omega necklaces.

The included black fabric cord (approx. 80 cm) is soft, supple, and provides very comfortable wear.
You will receive exactly the Boulder Opal pendant shown – a small, intense, unique play-of-color piece from Australia's nature.
