The Lightning - A boulder opal that looks like a lightning strike cutting straight through the stone, acting like a dark sky while that vivid central stripe flashes through it like a charged bolt. It ripples outward like illuminated clouds, and the red‑yellow hints give it that split‑second electric intensity - a strike frozen mid‑motion.
This striking boulder opal pendant features a long teardrop stone with vivid blue‑green colour play and a bold opal stripe running through the centre.
The rolling‑flash pattern gives the opal movement and depth, shifting beautifully as the pendant catches the light.
Ethically sourced from a miner in Queensland, this piece is set in solid 925 silver for a refined, timeless finish.
With a brightness level of 4 and polished surface, the colours appear strong and lively from every angle.
Its elongated shape makes it an elegant statement piece, perfect for everyday wear or special occasions.
A unique, one‑of‑a‑kind Australian opal pendant ready to find its new home.
