Aquamarine, emerald and morganite are all beryls – just like golden beryl, yellowish-green heliodor, colourless goshenite and the rare red beryl. Whether blue, green, yellow, colourless or pink, their chemical and physical properties essentially correspond; it is only in their colours that they differ from one another so much.
So where does this diversity come from? It is an exciting and very ancient story, which began millions of years ago when the appropriate pressure and temperature conditions formed precious crystals in the centre of the Earth. Beryls are beryllium-aluminium-silicates. As pure beryl, they are colourless, but they are able on account of their structure to store various foreign substances, and it is these which give rise to the various colours, turning a plain, colourless gemstone into a green, yellow, pink or blue treasure.
Facts:
- Mineral: Beryl
- Mohs Hardness: 7.5 to 8.0
