triangular gemstone pendant 3d model

Design a high-end luxury necklace in polished yellow gold with a refined triangular pendant. The pendant must have a clean, elegant triangular structure with slightly rounded edges, balanced proportions and a sophisticated commercial appeal. Each side of the triangle must have a distinct gemstone treatment: one side set with white diamonds (brilliant, refined, high sparkle) one side set with black diamonds (deep contrast, subtle shine) one side featuring imperial topaz as the main focal element (warm golden-orange tone, prominent but elegant) The composition should feel harmonious and luxurious, avoiding excessive complexity or overly conceptual design. The triangle should appear slightly dimensional (not flat), with soft elevation differences and a sense of depth, maintaining a premium jewelry aesthetic. The chain should be delicate and proportional, allowing the pendant to stand out. Style: high jewelry, Cartier/Bvlgari inspired, elegant, wearable, balanced, commercially appealing, c
