Firewater - A boulder opal pendant that looks like fire suspended in deep water, its blue base rippling beneath bursts of red, green and yellow flash that flare like embers drifting through a dark tide. Bold, fluid and full of movement, it has that rare mix of heat and cool that makes the whole piece feel alive.
This round boulder opal doublet pendant glows with a deep blue base and bursts of red, green, and yellow flash that ripple across its polished surface.
The colour play is bold and fiery, shifting beautifully as the light moves - a perfect mix of warmth and cool tones in one compact design.
Crafted as a boulder opal doublet, it offers a vibrant display of natural opal backed by ironstone for strength and durability.
Set in stamped 925 silver, this pendant feels effortlessly elegant yet full of character, ideal for everyday wear or gifting.
Each piece is miner‑direct and one‑of‑a‑kind, carrying the authentic story of Australian opal from earth to jewellery.
