Where the Tide Whispers - A veil of milky blue drifts across pale sand, carrying little glimmers of white like sea foam catching the morning light. Each turn brings another gentle ripple, a quiet reminder of the shore before the footprints, when the day belongs only to the tide.
This distinctive boulder opal pendant features a sandy ironstone base paired with a luminous white and milky‑blue opal face.
Almost the entire front of the stone displays colour, with a fascinating mix of broad flash, rolling flash and delicate pinfire creating movement and depth across the polished surface.
The low‑domed profile enhances the opal's natural glow, while the reverse reveals visible opal seams that tell the story of its formation within the ironstone.
The stone is framed in 925 silver around its edges, with an unusual split bail that adds an elegant finishing touch without distracting from the opal itself.
Miner‑direct and completely one‑of‑a‑kind, this pendant combines natural Australian character with a refined jewellery design.
