Which term describes something original that has value?

The term that best describes something original that has value is "a creation." This term encompasses any work that is formed, designed, or devised through imagination or effort, resulting in something unique and valuable. A creation can refer to a wide array of forms, including art, literature, music, and innovative products, all of which possess worth due to their originality and the thought put into them.

In contrast, a concept refers to an abstract idea or general notion that may not necessarily have tangible value on its own. A model typically represents a simplified version of something for demonstration or testing purposes, which doesn't inherently imply the value connected to originality. An invention, while also original, specifically pertains to a new product or process that has been created to fulfill a particular need, and may not always emphasize its artistic or conceptual value. Therefore, "a creation" is the most suitable choice to describe something that is both original and valuable.
