Gemstone Pendant made of Boulder Opal – with Fabric Cord

A compact, beautiful boulder opal pendant that captivates with its natural play of colors and earthy matrix. The polished stone displays the typical opal reflections – fine shimmers in blue, green, turquoise, or multi-colored – which light up and appear vibrant depending on the incidence of light.
The brown ironstone matrix forms a warm, powerful background and makes every boulder opal a unique natural piece with its own characteristic pattern.

Measuring approximately 21 × 17 mm, this pendant is subtle, elegant, and ideal for daily wear.
The 2.5 mm drill hole fits perfectly with leather cords, omega necklaces, or delicate silver chains.

The included black fabric cord (approx. 80 cm) is soft, pliable, and very comfortable against the skin.
You will receive exactly the boulder opal pendant pictured – a small, intensely colored treasure from Australia's nature.
