=Some crystals to look for in your sand specimens:=

The grains can appear brightly coloured because their surfaces have been polished by rolling around in rivers and the sea.

 * [[image:olivine crystal.jpg width="238" height="283" align="center"]]

Olivine - olive green
||

Garnet - mostly pink, orange or red.
||

Quartz - transparent
||
 * [[image:mica crystal.JPG width="257" height="233" align="center"]]

Mica/Muscovite - transparent flakes
||

Hornblende - shiny black
||

Feldspar - pink, white or red
||
 * [[image:pyroxene.jpg width="243" height="215" align="center"]]

Pyroxene - dark black
||

Plagioclase - white
||

Magnetite - dark grey-black
||
 * [[image:epidote.jpg width="266" height="237"]]

Epidote - lime green
||

Mica/Biotite - shiny black flakes
||

brown stains on other rocks.
|| =Colours of Quartz...=

Quartz occurs in many colours. The colours are caused by traces of different elements. Here are some examples...
