New research has led scientists to believe that diamonds may actually be easier to acquire than previously thought, and less expensive as a result. Diamonds aren't as rare as you might think ...
Diamonds, because of their hardness, are one of the few gemstones that have a recycled market. Recycled diamonds are diamonds that have been polished and set into jewelry, then removed and possibly re-cut before sale back into the diamond industry. This sector accounts for 5%–10% of market supply. [25]

Diamonds with higher color grades are rarer, in higher demand, and therefore more expensive, than lower color grades. Oddly enough, diamonds graded Z are also rare, and the bright yellow color is also highly valued. Diamonds graded D–F are considered "colorless", G–J are considered "near-colorless", K–M are "slightly colored".
Although diamonds on Earth are rare, they are very common in space. In meteorites , about three percent of the carbon is in the form of nanodiamonds , having diameters of a few nanometers. Sufficiently small diamonds can form in the cold of space because their lower surface energy makes them more stable than graphite.
Scientists analyzed 46 blue diamonds, including one that sold for $25 million in 2016, and determined that they can form at depths of at least 410 miles Rare blue diamonds may be Earth's deepest ...
Type II diamonds have very few if any nitrogen impurities. Pure (type IIa) diamond can be colored pink, red, or, brown owing to structural anomalies arising through plastic deformation during crystal growth; [20] these diamonds are rare (1.8% of gem diamonds), but constitute a large percentage of Australian diamonds. Type IIb diamonds, which ...
