Physically based 3D render of prismatic glass hearts arranged in a vertical 2:3 composition. A vertical stack of clear crystal hearts refracts vibrant light, casting colorful rainbow patterns across a soft-focus velvet background. Sharp directional lighting emphasizes the multifaceted surfaces and high-specular highlights of the glass. The vertical orientation captures the 'jewelry-like' quality of the hearts as they ascend through the frame. The background is a deep plum color, providing a rich contrast for the brilliant glass. The aesthetic is intricate, high-end, and romantically bold.
