The color is subtle rather than saturated, allowing bright white reflections to break through the warmer body tone as the stone moves.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eIts softly squared cushion outline has the gentle asymmetry and character associated with antique-style cutting. Against the hand, the warmth becomes especially apparent, while darker surroundings bring out stronger contrast between its golden facets and flashes of cool white light. The result feels luminous and distinctly old-world rather than perfectly uniform—a natural diamond with warmth, movement, and individuality.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eThe Lapidary’s Eye\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003e\u003cspan\u003eThe Old Mine Cushion Cut gives this diamond a deeper 4.34 mm profile and a lively arrangement of varied facets.
