The Blue Hour Awakens - A streak of electric blue breaks through the deepening dusk, scattering white sparks across the quiet. For a moment, the world holds its breath, caught between the last light of day and the first stars waking.
This striking solid boulder opal pendant showcases vivid electric blue, deep blue and white flashes across its polished full‑face surface. The colour play combines rolling flash and pinfire patterns, creating a dynamic display that changes beautifully as the stone moves.
With brightness 5, the flashes are bold, luminous and impossible to ignore.
Its unusual elongated rectangular shape gives the pendant a contemporary feel while preserving the natural character of the stone. Measuring 31 × 11 × 3 mm, it is lightweight and comfortable to wear, suspended from an adjustable leather cord that complements the opal's organic beauty.
Sourced directly from the miner, this one‑of‑a‑kind Australian boulder opal is a perfect example of how spectacular solid opal can be when bright colour and natural form come together.
