Beryl Aquamarine

Beryl crystallises as prisms that often terminate in pyramidal forms and are striated in the direction of elongation. These minerals form crystals of considerable size. When pure, beryl is colourless, but it also takes on other colours depending on the variety: green (emerald), yellow (heliodor), pink (morganite), red and blue (aquamarine). It does not melt easily and is not easily attacked by acids.

It forms mainly within granites, granitic pegmatites and metamorphic rocks.

Pure beryl is used for the production of ultralight alloys, above all in the aeronautical industry. In the other varieties mentioned (emerald, heliodor, morganite and aquamarine) it is widely used in jewellery.
