In photorealistic lifelike 4K a stunningly beautiful intricately detailed futuristic high-tech mechanical motion pendant in the shape of a small ((three-dimensional bipyramid shaped)) open-framework futuristic high-tech ultramodern non-terrestrial device inspired by the Antikythera Mechanism Greek analog computer jewelry ((constructed from highly polished shiny reflective Obsidian with reflective brass and Copper trim)) as well as several (diamond and ruby and Pearl gemstones) giving it a very non-terrestrial appearance and the design incorporates ((intricate illuminated internal circuitry giving off a neon pink glow)) that adds to its otherworldly look also ensure that the device has a highly detailed and complex mechanized bipyramid shaped self-rotating mechanical structure reflecting advanced technology and non-terrestrial sweeping geometric symbols embossed on its exterior surface as well as small illuminated indicators also The image should be visually striking and imaginative, capturing the viewer's attention and sparking curiosity about the possibilities of future non-terrestrial technology. Highly detailed and extremely intricate interwoven and overlapping mechanical and electrical circuitry with a single small ovoid shaped convex display screen showing strange non-terrestrial sweeping geometric symbols. Many moving external components designed to depict and display a moon orbiting a planet. Many illuminated moving gemstone components showing moon orbiting a planet ((with a gorgeous perfectly faceted illuminated center stone)).
