Sunstream Crest - A vivid full‑face opal glowing with shifting colour, its dimensional shape catching the light like ripples flowing over a sunlit tide.
This bright full‑face solid boulder opal pendant features an unusual sculpted freeform shape that isn’t flat, giving it a natural, dimensional feel.
The stone shows vivid green, blue and white broad rolling flash with brightness 5, shifting beautifully across its polished surface. Fully double‑sided, the back displays natural opal matrix and colour, making the pendant reversible.
The 20 × 19 × 2 mm opal hangs on an adjustable leather cord, keeping the design earthy while letting the rare shape and intense colour take centre stage.
A miner‑direct solid opal perfect for collectors who love bright natural colour and unique organic forms.
