Earthwater - A boulder opal that looks like clear blue water rising from the dark earth, the vivid blue‑green broad flash lifting upward like a glowing spring pushing through ironstone. The teardrop shape makes it feel even more like a rising pool of light - calm, bright and beautifully grounded in its natural matrix.
This polished Australian Boulder Opal cabochon glows with a vivid blue‑green broad flash that catches the light beautifully.
Cut into a smooth teardrop shape, it’s a versatile stone ready for jewellers, wire‑wrappers, or collectors who appreciate natural opal character and miner‑direct sourcing.
Ethically mined and polished in Queensland, this opal’s brightness level 3 gives it a lively shimmer without overpowering its earthy ironstone base - a perfect balance of colour and authenticity.
