#MinCup23 Asparagus has a special place in the heart of us Germans, so I was happy to learn that there is a greenish variety of #fluoroapatite that is called Spargelstein (asparagus stone). Also it shows luminescence under UV light. Very pretty, but...#Zircon is a colorful gemstone which is host matrix for e.g. rare earth elements and uranium and thorium, which makes zircons extremely useful for geochronology. And it can be produced synthetically e.g. for jewellery.
