"Swiss Breakthrough Simplifies Diamond Detection for Hunters"

A new study led by Andrea Giuliani has found that the iron-to-magnesium ratio in olivine, a mineral in kimberlite rock, is directly related to the presence of diamonds. The research, supported by De Beers, revealed that olivine becomes richer in iron due to metasomatism, a process in the earth's interior, which destroys diamonds. Conversely, when no metasomatism occurs, olivine contains more magnesium, preserving the diamonds. This new olivine analysis method is now being used by De Beers as it provides a simpler and faster way to detect diamond deposits.

Uncovering Clues to Rare Pink Diamonds: From Supercontinent Breakups to Volcanic Revelations

Researchers studying the Argyle diamond deposit in Western Australia have gained a better understanding of the geological conditions necessary for the formation of pink diamonds. Using lasers to analyze minerals and rocks, they discovered that the pink diamond-rich site formed during the breakup of an ancient supercontinent called Nuna, around 1.3 billion years ago. The study suggests that the junctures of ancient continents may be important for finding pink diamonds and could guide exploration for other deposits.
