Why study and synthesize #Ringwoodite? Experiments (below, a diamond anvil pressure device that's transparent to visible light; Schmandt et al, 2014) and natural samples from the Earth's mantle (see ksircombe's posts: https://aus.social/@ksircombe/113124213223248687) suggest that there's an ocean or two worth of water stored in Earth's Ringwoodite. It's likely kept the planet habitable for the last 4.5 billion years.
Plus Ringwoodite is more Blue than #Kyanite !

Attached: 1 image 4/ Analysis of the ringwoodite from the diamond showed it contained 1.5% water. May not seem like a lot, but a lot of ringwoodite in the mantle means a lot of water down there too. This has big implications the origins of the oceans and how plate tectonics works. https://bib-pubdb1.desy.de/record/168146/files/10.1038_nature13080.pdf
