Beryl is a mineral composed of beryllium aluminium cyclosilicate. The Blue colour is from trace elements of Iron.
Beryl is often unknown to the general public. It is one of the most important gem minerals. Beryl is colorless in pure form, it is the many different impurities that give Beryl its varied colouration. Without these splendid color varieties, Beryl would be a rather ordinary gemstone with only average fire and brilliance. Emerald is the green variety and Aquamarine is the blue variety of Beryl.
Other colors of Beryl are also used as gemstones but are not as well known.
The greenish-yellow variety is called Heliodor.
The pink variety is called Morganite.
The colorless variety is called Goshenite.
The red variety is called Bixbite.
The name Beryl is used for the golden varieties, which is simply called Golden Beryl.
Quartz is one of the most common minerals found in the Earth’s crust. If pure, quartz forms colorless, transparent and very hard crystals with a glass-like luster. A significant component of many igneous, metamorphic and sedimentary rocks, this natural form of silicon dioxide is found in an impressive range of varieties and colours.
Quartz in it’s polished form was the most advanced technology thousands of years ago, used by the Assyrians. Quartz was used as a lens to focus light and could start a fire. The Vikings would have used one of these to find the sun on a cloudy day. It would have been used as a magnifying glass too. Today it leads technology being the main component of transistors which make our computers work and solar panels.
