Аметистовый кристалл — вариант 1

Use case: product-mockup. Use the supplied image as the exact reference. Create one isolated transparent PNG of a single upright elongated amethyst crystal cluster: one tall dominant pointed central crystal with faceted hexagonal sides and a few shorter rough crystal shoulders at its lower sides. Explicit color: saturated violet and lavender core facets with cool icy-silver and pale lilac facets; shift the violet somewhat toward blue-amethyst while keeping silver highlights. Pose and angle: crystal standing upright, three-quarter view, pointed tip leaning very slightly left as in reference. Framing: medium close product shot, full cluster visible and centered on a square canvas at about 75–80 percent height, with transparent padding. Preserve natural mineral translucency, crystalline striations, sharp facets and soft diffuse upper-left studio lighting. Make the side crystal shoulders a little more distinct and asymmetric while retaining the same amethyst cluster identity. True transparent alpha around the entire mineral; no base, floor, glow outside, backdrop, external shadow, text or extra objects.
