A hyper-realistic sapphire gemstone, meticulously modeled to reflect its natural hexagonal crystal structure with smooth, polished facets that catch and refract light. The deep blue hue is vibrant with subtle variations in saturation, giving it a lifelike appearance, while the surface may feature minor inclusions or imperfections to enhance realism. The gem is set in a simple, yet elegant metal holder, possibly tarnished or slightly worn to fit the survival horror aesthetic.
