Corundum

The word corundum comes from the Tamil word kurundam, which means “ruby” or “sapphire.” Ancient civilizations prized these gemstones for their beauty and durability, often associating them with power, protection, and wisdom.

Rubies and sapphires are among the most sought-after gemstones. Rubies symbolize passion and protection, while sapphires represent wisdom and nobility.

Corundum is the mineral species, while ruby and sapphire are gem-quality varieties. All rubies and sapphires are corundum, but not all corundum is a ruby or sapphire.
