Emblema 3D di Lusso con Pavé di Diamanti

Luxurious 3D emblem render of a large standalone [X] symbol centered upright on a glossy black reflective surface. Thick, angular, and beveled geometry with a polished metallic [gold] outer rim and inner raised edges. The recessed front face is densely encrusted with tiny faceted [black diamond] stones in a pavé setting, catching subtle specular highlights. Dramatic low-key studio lighting with a warm golden rim glow and sharp starburst glints at four specific points: upper-left tip, upper-right tip, lower-left edge, and lower-right edge. Soft mirror reflection cast on the surface below. Deep charcoal background with subtle vignette and faint overhead spotlight haze. High contrast, clean luxury jewelry aesthetic, crisp bevels, square 1:1 composition without any text or watermarks.
