Emerald Infinity Stone on a Tropical Beach

Photorealistic close-up of a single emerald-green Infinity Stone embedded in pristine white sand on a tropical beach at golden hour. The gem emits a pulsing emerald glow, casting neon-green reflections on the wet sand and tiny droplets. Faceted surface shows precise light refraction, minute scratches and a subtle halo. Background features turquoise waves washing the shore, palm trees framing the horizon, and a warm sun low in the sky. Shot with a 50mm macro lens, shallow depth of field, ultra-detailed texture, high dynamic range and cinematic lighting.
