What is the most common color of untreated, natural topaz?

The most common color of untreated, natural topaz is colorless. While topaz can occur in various colors due to natural processes, including blue, pink, and yellow, the clear, colorless variety is frequently found in nature. This is largely due to the mineral's natural composition, which allows it to be colorless when free of impurities and structural defects. Many colored topaz stones available on the market are often the result of treatments or enhancements, such as irradiation or heating, which modify the stone’s inherent color. This means that if one seeks untreated natural topaz, they are most likely to encounter the colorless form, as it represents the stone in its purest state. Thus, colorless is considered the standard or most common appearance of untreated topaz.
