What company has the most expensive cube?

Could you please clarify which industry or field you're referring to when you ask about the "most expensive cube"? Is it in the realm of art, technology, luxury goods, or something else entirely? Depending on the context, the answer could vary significantly. For instance, in the world of luxury goods, there may be a high-end jewelry company that has crafted an exquisite diamond-encrusted cube that fetches an astronomical price. Alternatively, in the tech industry, a cutting-edge data storage cube from a pioneering company might command a hefty price tag due to its unique capabilities and innovative technology. Without further context, it's difficult to pinpoint a specific company with the most expensive cube.
