Most of Earth's diamonds formed billions of years ago, during the supercontinent cycle, as carbon fragments around 100 miles deep were crystallized by unimaginable forces of heat and pressure. But diamonds can also flash-form due to meteorite impact.

In Diamond 4Cs analysis, clarity evaluates a gemstone’s relative freedom from inclusions and blemishes. There are 11 different clarity grades which descend gradually from flawless. However, nuanced gemological analysis notwithstanding, many buyers just want to know, is it "eye-clean?"
The legendary Mir Diamond Mine, built at the order of Joseph Stalin, had a surface operation which lasted 44 years. The recent discovery of an estimated 38 million carats of diamond reserves at Mir have now led to optimism from Mining giant Alrosa about its restoration and further development.
