Yes, there are several ways to distinguish between a natural and a synthetic diamond. One of the most common is by examining its fluorescence under ultraviolet light. Natural diamonds will glow green or yellow-green, while synthetic diamonds will glow blue or white. Additionally, natural diamonds tend to be more expensive than their synthetic counterparts due to the difficulty in finding them and the high cost of mining.
