Handleiding

Certain crystals will vibrate when electric current passes

through them. Many clocks use quartz

crystals to ensure

the watch keeps accurate time. Early radio transmitters used

different types of crystals to create the frequencies to transmit

signals.

Quartz is the most commonly found crystal on earth.

Crystals are often used in jewelry. There are four types that

are considered the most valuable and commercially referred

to as precious stones. These are diamonds

, emeralds

rubies

, and sapphires

When we think of crystals we often think of beautiful

gems. But did you know that snowﬂakes, sugar, sand, and salt

are also crystals?

Colombia is the world’s largest producer of emeralds,

providing more than 50% of the world’s production.

A diamond needs only one building block to form: carbon

atoms. Diamonds are typically made deep inside Earth by

carbon atoms being pushed together with amazing amounts of

pressure and high temperatures.

Some of the largest crystals ever found are in a cave in

Mexico called the Cueva de los Cristales (Cave of the Crystals)

. This cave is ﬁlled with gypsum crystals that are up to 36

feet long.

Diamonds are the hardest natural material on Earth and

are often used for cutting other stones or in polishing tools.

Most minerals occur naturally as

crystals. Many minerals are actually

colorless but if there are impurities

present when the crystal is forming

they can form in different colors.

Quartz traditionally is clear, but if iron

or manganese impurities are present

during the quartz formation

you will get a purple

quartz called

amethyst
