Large Oval Cut Star Sapphire on Dark Velvet Stock Image - Free Download

A high-end macro photograph of a massive, oval-cut star sapphire gemstone resting on a dark charcoal velvet cushion. The gemstone exhibits a deep, royal blue hue with a sharp, brilliant six-rayed asterism star cutting across its center, triggered by a precise single light source from above. Soft side-lighting highlights the crystalline facets and the smooth, polished surface of the stone. The background is a moody, blurred luxury jewelry display setting with subtle bokeh. Shot on 100mm macro lens, f/8, sharp focus on the star effect, realistic mineral textures, no synthetic glow, cinematic lighting, 8k resolution.
