In my former role working in the Natural Sciences department at the National Museums of Scotland, there was one object in particular that stood out - a stunning Blue John vase. Standing probably about two foot tall and having been carved from a single piece, it was one of the Mineralogy section's treasures, and rightly so.
So yesterday when I heard about the discovery of a Blue John vein that has been a mystery for almost seventy years, I thought it was a neat story to share.
Blue John is a very rare and beautiful variety of fluorite, found in Derbyshire, England - the only known locality in the world. In 1945 an "amazing" vein deposit was found but the miner died before he could show anyone exactly where it was. The family that ran the caverns (where the Blue John is mined) have searched for it ever since. Only now has it been found, solving this decades old mystery. This video and article from the Yorkshire Post explains it all.
