Cassiterite

1. Introduction & History

• Origin of the Name: Derived from the Greek 'Kassiteros,' meaning tin. The name traces back to the ancient Greeks, who called the tin-rich lands of Western Europe the 'Cassiterides' (the Tin Islands).
• Historical Background: Cassiterite is the most important tin ($SnO_2$) ore in human history. It played a central role in making bronze — the alloy of copper and tin that propelled the great leap of civilization in the Bronze Age — and has accompanied humanity for thousands of years.

• Value Criteria: Fairly common as ore, but transparent gem-quality crystals are very rare and highly valued by collectors around the world.

6. Care Guide

• Cleaning: Wipe gently with lukewarm water and a soft cloth. Avoid ultrasonic cleaners and harsh chemical detergents, which can damage the surface and structure of the stone.
• Cleansing: Moonlight, the vibration of a singing bowl, or the smoke of sage incense are the safest methods.
• Cautions: At Mohs 6–7 it is fairly hard, but its cleavage makes it somewhat vulnerable to impact. Take care not to drop it or let it strike other hard objects.
