Luxury jewelry brand U-Treasure has partnered with Japan’s premier occult and mystery magazine, MU, to release a series of high-end collectibles based on famous OOPArts (Out-of-Place Artifacts). The collection, which opened for pre-orders today, April 7, features limited-edition replicas made of solid gold and silver.

The flagship item of the collaboration is the Solid Gold Ancient Jet, priced at 1,650,000 yen. Limited to just 10 pieces worldwide, it's a 24-karat gold recreation of the mysterious aerodynamic figurines found in Colombia. The collection also includes a Solid Gold Shakoki-dogu, a miniature version of Japan's famous prehistoric clay figurines often associated by mystery enthusiasts with ancient astronauts.

Supervised by the MU editorial team to celebrate the magazine's ongoing legacy of exploring world mysteries, these products target both serious collectors and fans of the paranormal. Pre-orders will remain open until May 7, 2026, via U-Treasure’s online and physical stores.
