Diamonds are Forever

Diamonds are Forever

16 July

Diamonds tell a story that has travelled through history, far longer than our ownership of them and the memories which we attach to them.

Diamonds are over 900 million years old in most cases, even reaching ages of 3.5 billion (yes billion with a b) years old.The name diamond is derived from the ancient Greek αδάμας, diamonds are thought to have been first recognised and mined in India, where significant alluvial deposits of the stone could be found many centuries ago along the rivers Penner, Krishna and Godavari.

Diamonds have been treasured as gemstones since their use as religious icons in ancient India. Their usage as engraving tools also dates to early human history. The popularity of diamonds has risen since the 19th century because of increased supply, improved cutting and polishing techniques, growth in the world economy, and innovative and successful advertising campaigns.

The most familiar use of diamonds today is as gemstones used for adornment, and as industrial abrasives for cutting hard materials. In the 20th century, experts in gemmology developed methods of grading diamonds and other gemstones based on the characteristics most important to their value as a gem. Four characteristics, known informally as the four Cs, are now commonly used as the basic descriptors of diamonds; these are carat (its weight), cut (quality of the cut is graded according to proportions, symmetry and polish), colour (how close to white or colourless, for fancy diamonds how intense is its hue), and clarity (how free is it from inclusions). A large flawless diamond is known as a paragon.
