Malachite - the intensely banded green copper carbonate mineral whose characteristic concentric swirl patterns in deep and lighter greens make each specimen uniquely beautiful - in a freeform setting at 2.64 carats creates a ring where the natural organic character of the stone and the warmth of 18K yellow gold over sterling silver meet. The freeform shape means the stone has been shaped to honor its natural form rather than calibrated to a standard size, allowing the malachite's distinctive banding to be preserved and displayed as nature created it. Each malachite freeform ring is therefore genuinely unique - the specific banding pattern of that stone, in that orientation, unrepeatable.
