GEMSTONE PROVENANCE TAKES CENTRE STAGE IN THE LATEST JEWELS FEATURING THE FINEST RARE MINERALS

The strongest naturally occurring substance on earth, diamonds were first referenced in Sanskrit texts as early as 400BC. Coloured diamonds, however, are extremely rare with only one natural coloured stone found for every 10,000 colourless diamonds. Factors that determine a coloured diamond’s value include hue, tone and saturation. Microscopic amounts of trace elements and distortions, pressure or carbon atoms interacting with an element can effect a colour change in diamonds. For instance, the presence of hydrogen creates pink, purple and red diamonds, while boron absorption results in blue diamonds. The mines where these rarities are discovered are quickly becoming depleted, making them even more heart-stoppingly expensive.

Cut and polished from an extremely rare 13.33-carat pink rough diamond discovered at the renowned Letseng mine in Lesotho, it was purchased by Laurence Graff for over US$8.7 million (S$12.1 million), breaking the record dollar per carat price of any Letseng diamond.
