Quizplus · Accepted Answer

Color is often an unreliable diagnostic property of minerals as it can be affected by impurities or variations in lighting conditions. Quartz, for example, can occur in a range of colors including colorless, white, gray, pink, yellow, and even purple or black. Therefore, relying on color alone to identify a mineral like quartz can lead to mistakes.
