It is usually tan, brown, or reddish in color, and often (but not always) displays noticeable layers. The sand grains are most often made of quartz, cemented together by calcite or silica.

All coquina is clastic and fine- to medium-grained, meaning that it is made up of fragments and that those fragments range in size from about 1/16 mm and above. These fragments are visible to the naked eye, but if you really want to get a good look at them I would highly recommend a good geologist’s hand lens .
