- A Kimberlite diamond sample from Brazil, formed as deep as 600km beneath the surface, and containing one percent water, suggests that the interior of the earth may contain more water than previously imagined http://www.bbc.com/news/science-environment-26553115#? 4 comments science
- It may be raining diamonds on Saturn and Jupiter, according to two planetary scientists. They claim soot in the atmosphere is compressed into solid diamonds before melting to form liquid diamond raindrops. http://www.nature.com/news/diamond-drizzle-forecast-for-saturn-and-jupiter-1.13925 20 comments science

- Change in enthalpy for transition of carbon in the diamond form to carbon in the graphite form is apparently a negative number (-453.5 cal). According to this, graphite is more stable than diamond, how’s that possible? Isn’t diamond supposed to be stronger and more stable than any other material? https://www.reddit.com/r/askscience/comments/9l98lb/change_in_enthalpy_for_transition_of_carbon_in/ 8 comments askscience

- Scientists discover that the composition of the Earth's mantle may be significantly different, after compressing a sample with diamonds, hitting it with a laser, while simultaneously X-raying the sample. The sample formed into two different minerals, one of which still isnt completely understood. http://www.sciencedaily.com/releases/2014/08/140826152813.htm 11 comments science
- Diamond rain may be more common across the universe than we thought: It may be easier than researchers thought to form diamonds inside giant planets, which means that it might rain diamonds on up to a third of the planets we’ve discovered so far https://www.newscientist.com/article/2411384-diamond-rain-may-be-more-common-across-the-universe-than-we-thought/ 4 comments space
- Scientists (EPFL) have examined a slice from a meteorite that contains large diamonds formed at high pressure. The study shows that the parent body from which the meteorite came was a planetary embryo of a size between Mercury to Mars. The discovery is published in Nature Communications. https://actu.epfl.ch/news/meteorite-diamonds-tell-of-a-lost-planet/ 3 comments science

The Earth’s deepest diamonds are commonly made up of former living organisms that have effectively been recycled more than 400 kilometres below the surface, new Curtin research has discovered. https://www.scimex.org/newsfeed/new-curtin-research-shows-mother-nature-recycles-trash-to-create-diamonds 31 comments science
- 24 “superdeep” diamonds contain ratios of helium isotopes far different from those found on most of the planet. Scientists suspect these diamonds, which formed over 100 miles below the Earth’s surface and remained isolated for billions of years, reveal a glimpse of the planet’s early years. https://www.inverse.com/article/58519-superdeep-diamonds-window-into-chaotic-early-earth 501 comments science
