Crystalline Blue Heart on Dark Stone Radiant.

Positioned against a dark atmospheric background, this transparent blue crystal assumes a perfect heart form, its faceted surface refracting brilliant light into layered azure and turquoise tones. Resting on a dark mineral base, the luminous gem exhibits intricate internal fractures and prismatic reflections that create dimensional depth. Sharp geometric planes catch overhead illumination, while translucent areas glow with ethereal intensity, establishing striking contrast between the gemstone's radiance and its shadowed surroundings.
