Meet Sunflower,

An Australian Fire Opal Engagement Ring from Lightning Ridge, Framed in 18k Gold & Diamonds

Like the golden petals of a sunflower reaching toward the sun, this estimated 4.30ct Lightning Ridge crystal fire opal radiates warmth and light.  Its vibrant rolling red flashes shift to a steady green glow, a mesmerizing effect that changes with movement.  The opal’s rare fire is enhanced by a delicate halo of 16 natural diamonds, each one catching the light like dewdrops on flower petals.

Crafted in solid 18k gold, this ring blends elegance with structure.  The yellow gold shank provides a rich foundation, while the white gold halo setting lifts the diamonds to maximize their brilliance.  Designed with Japanese craftsmanship, the ring’s precise edges and bold structure give it a strong, architectural presence– delicate in design yet built to last a lifetime.

Whether chosen as a unique engagement ring or a rare collector’s piece, this opal is one of nature’s finest works of art, encased in a setting worthy of its brilliance.

Default ring size 6.00 US.
