• She was wearing a crystal pendant.

• We bought them a set of crystal bowls.

• Alteration is variable: absent in many crystals, in others producing dense sericite aggregates which may show some recrystallization effects to produce coarser-grained white mica.

• The tridymite crystals are rectangular or wedge-shaped and are sometimes arranged in aggregates.

• In addition, haloarchaeal cells were embedded within salt crystals under laboratory conditions and subsequently analysed by light microscopy.

• The white clouds (usually sparse) were also widely regarded as being composed of tiny crystals of water ice, rather like cirrus in our atmosphere.

• They are found in evaporite salt lakes and can be trapped in salt crystals during evaporation.

• Therefore, the cells (organelles and membranes) are destroyed mechanically by ice crystals, leading to death through cell lysis.
