The Wishing Path - Between the winding paths of an old garden, green, gold, blue and violet lights begin to glimmer. Follow one and another appears, until every turn feels like the beginning of a small adventure.
This beautiful matrix‑conglomerate Yowah boulder opal necklace displays flashes of green, yellow, blue and purple woven through its polished surface. The natural matrix pattern creates a mosaic‑like appearance, with vibrant pinfire colour scattered throughout the stone.
Fully double‑sided, the pendant reveals natural character and detail from every angle, making it as interesting from the back as it is from the front.
The freeform shape enhances the organic feel of the piece, while brightness 4 ensures the colours remain lively and visible in a variety of lighting conditions.
Suspended from an adjustable leather cord, this miner‑direct Australian boulder opal combines earthy textures with colourful flashes for a truly unique statement piece.
