Аметистовый кристалл — вариант 2

Use case: product-mockup. Use the supplied image as the exact reference. Create one isolated transparent PNG of the same upright amethyst cluster, preserving a tall pointed main crystal, prominent faceted hexagonal body, lavender-violet interior and icy silver facets. Explicit palette: natural amethyst purple, pale lilac and cool silver, with a few restrained rose-lilac reflections. Pose/angle: standing upright, viewed from the same slightly elevated three-quarter angle, main tip near the top center. Framing: medium close-up of the whole crystal cluster with transparent square margins, no cropping. Keep realistic polished mineral translucency, internal veining and soft upper-left studio light. Make a moderately distinct form sibling: the main crystal slightly wider through its middle with a shorter, more angular point, and one small secondary crystal jutting from the lower right; keep the cluster recognizable as amethyst. Genuine alpha transparency outside the cutout, no rock base, scenery, background, external shadow, text, logo or other objects.
