A dark blue geometric triangle with crystalline facets on a black background.

Create a minimalist yet realistic triangle logo with a dark blue gemstone appearance. The triangle should be clean and geometric, featuring subtle crystal-like facets and a deep sapphire or navy blue color. The logo should have a polished gem texture with light reflections and a soft internal glow — but stay simple and iconic, not overly complex. Style it to be sleek and modern, with enough clarity to work well as part of a SoundCloud banner. Use a dark or transparent background to make the triangle stand out, and keep the design balanced and professional. See more
