What word can be used to refer to a showy ornament that is without much value?

The term "gaudy" is commonly used to describe something that is showy or overly ornate, often in a way that lacks taste or sophistication. This word carries a connotation of being flashy and attention-grabbing without possessing true value or quality. It typically implies a kind of extravagance that is more about superficial appearance than substance or elegance, thus fitting the context of being an ornament that is not particularly valuable.

In contrast, other options like "exquisite" denote something that is beautifully made or of exceptional quality, "ornate" refers to something richly decorated but does not inherently imply a lack of value, and "simple" suggests a lack of complexity or adornment. Thus, "gaudy" accurately encapsulates the idea of a decorative item that stands out but lacks meaningful worth.
