Read each of the following paragraph and underline the topic sentence.

Although color is generally the most conspicuous characteristic of a mineral, it is considered a diagnostic property of only a few minerals.

Other minerals, such as minerals, such as tourmaline, also exhibit a variety of hues, with multiple colors sometimes occurring in the same sample. Thus, the use of colors as a means of mineral identification is often ambiguous and even misleading.
