From the ancient, sun-forged terrain of Queensland, Australia, Cor Ardens—Latin for “burning heart”—emerges with quiet intensity and natural grace. Shaped in an elegant oval with a low dome, this 21.80ct boulder opal reflects not only light, but a sense of stillness touched by flame. With a B3 brilliance, it reveals a balanced and vivid play of colour—blue, green, and purple shimmer gently across its surface like shifting light on water. These hues rise clearly under natural light, offering a steady, enchanting glow that speaks of inner fire and subtle depth. Cool tones ripple across the stone like wind through eucalyptus leaves, while deep purple sparks suggest a quiet ember burning beneath. Cor Ardens is a piece suspended between serenity and flame, timeless and alive.
