4.66ct Solid Australian Boulder Opal

£500.00 £1,650.00

Overview:

This solid natural Australian Boulder Opal is a breathtaking display of nature’s artistry — a gem alive with vivid pinfire multicolors that dance across its polished surface.

From every angle, the stone bursts with electric flashes of neon green, fiery orange, golden yellow, and deep sapphire blue, all interwoven in a fine pinfire pattern that glitters like a galaxy under light. The oval cabochon cut enhances its play-of-color, giving the opal a luminous depth and a smooth, tactile finish that feels luxurious in hand.

The body tone is a balanced medium-dark base, allowing the colors to ignite vividly against the natural ironstone backing — a hallmark of true Boulder Opal. Its solid formation (not a doublet or triplet) ensures enduring value and authenticity, with the natural host rock visible along the edges and back, confirming its origin from Queensland’s famed opal fields.

This gem’s 3.8mm thickness gives it excellent durability for fine jewellery settings — perfect for a statement ring or pendant. Under direct light, the opal’s pinfire pattern transforms into a kaleidoscope of color, shimmering with every movement.
