In Ancient Rome, wealthy Romans always drank from goblets made from clear rock crystal. They believed the transparent mineral was a safeguard against their enemies, because legend had it that a cup carved from the transparent mineral would not hold poison.

The Roman writer Pliny was amazed that his fellow citizens were willing to pay huge prices for this real crystal, when there was readily available cheaper glass that looked very similar.

Sunglasses made of colored rock crystal are supposed to have been worn in China, during the Ming dynasty (1368–1644). They were popular with judges who believed that the glasses would conceal their facial expressions while questioning witnesses during court sessions.

Henry Ford maintained that eating sugar was tantamount to committing suicide as its sharp crystals cut a person's stomach to shreds.

The Cave of Crystals in Chihuahua, Mexico, contains giant gypsum crystals more than 36 feet long and weighing up to 55 tons.

Tiny ice crystals fall and join with others to form a snowflake. The size of a snowflake depends on how many crystals hook together.

At the center of almost every snow crystal is a tiny mote of dust, which can be anything from volcanic ash to a particle from outer space.
