Planet earth's geological history is fascinating. Within this history, Diamonds are earth’s oldest preserved minerals and have captured human imagination, unlike any other mineral. Diamonds are geological masterpieces, forged by nature, billions of years ago. Until 1725, India was the world's only source of diamonds, followed by the discovery of diamond mines in Brazil. Countless diamond discoveries were made, mostly alluvial, till diamond mining became a preferred method of recovering diamonds.
