What is the origin of the word "diamond" and where were the earliest known diamonds mined?

• A. The word diamond derives from the Greek "adámas" meaning unconquerable, via Latin "diamanten"; the earliest known mining occurred in India (Golconda).
• B. The word diamond comes from Latin "diman" meaning bright, with earliest mining in Brazil.
• C. The term diamond is borrowed from Arabic "dhahab" meaning gold, and the earliest mining occurred in South Africa.
• D. The word diamond originates from Greek "adámas" meaning invincible, but earliest mining occurred in Australia.

Answer: (A)

The question is about where the word diamond came from and where diamonds were first mined. The word diamond comes from the ancient Greek adámas, meaning invincible or unconquerable, and it reached English through Latin forms such as diamanten or diamans, with the sense carried into Old French as diamant and then into English. This lineage reflects how European languages borrowed the term from a Greek root that highlighted the stone’s legendary hardness.

As for where diamonds were first mined, the earliest known sources are in India, especially in the Golconda region and the Kollur mine area, where alluvial deposits were worked long before other regions became prominent. Indian diamonds circulated in ancient trade networks and were valued for their brilliance and durability long before diamond mining developed elsewhere.

So the best choice aligns with the Greek-origin root meaning “invincible” and with India as the site of the earliest diamonds mined. The other options mix incorrect etymologies and place earlier mining in locations that did not historically yield the earliest diamonds.
