Gemstone Pendant made of Boulder Opal – with Fabric Cord

An impressive boulder opal pendant that captivates with its fascinating play of colors and characteristic natural matrix. The polished gemstone displays the typical luminescence of opal – delicate to intense flashes of color in blue, green, or multicolored, which change vibrantly depending on the light.
The warm, brown ironstone matrix creates a beautiful contrast to the opalescent shimmer, making each boulder opal a distinctive natural unique piece.

With a size of approximately 31 × 18 mm, the pendant appears balanced, elegant, and pleasantly present at the same time.
The 2.5 mm hole is ideal for leather cords, thin silver chains, or omega necklaces.

The included black fabric cord (approx. 80 cm) feels soft on the skin, is supple, and offers high wearing comfort.
You will receive exactly the boulder opal pendant shown – a natural work of art full of depth and colorful vibrancy.
