#MinCup23 Here's a gorgeous big zircon crystal in a rock thin section of a Lewisian gneiss from Rodil in South Harris. Field of view about 2mm wide. 🥰 🤩 #VoteZircon #Geology #Mineralogy #Lewisian

A view of a rock under of a polarized light microscope, using crossed polars.most of the crystals in the rock appear black and white, or grey, but in the centre of the view, a large rounded crystal is greenish yellow in colour.

A view of a rock under of a polarized light microscope, using plane polarized light. Most of the crystals in the rock appear colourless, but in the centre of the view, a large rounded crystal stands out strongly, with. To the left of this crystal is a zone rich in smaller black, brown and green crystals.

@inoru_no_hoshi booo! 😁 #VoteZircon

#MinCup23 Vote #Zircon!! Here's a gorgeous big chestnut zircon from the excellently-named Mud Tank carbonatite, in Northern Australia. This one, which I bought in Tucson in 2006, is nearly 4cm long. *AND* this crystal also glows gold in 254nm UV light!! Vote for truth and beauty - #VoteZircon 😊 👍 #Geology #Mineralogy

A lustrous deep brown crystal, with limpid transparent depths sits on a blue velvet background. A white scalebar along the bottom of the image shows the size - just under 4cm!

A glowing golden luminous crystal appears to sit floating in dark space.

#MinCup23 Green, brown and yellow gem-quality zircons from the legendary gem gravels of Ratnapura, Sri Lanka 🤩 😋 🥰 #VoteZircon #BestMineral

A cluster of 25 small sparkly, transparent, gem-like pebbles of zircon, in various shades of green, brown and yellow, on a white paper background, with a black-and-white cm scalebar at the bottom of the picture.

#MinCup23 Vote 🥰 Zircon🥰 . There's an awful lot of giant zircon in ultramafic gneisses of the Lewisian complex. 254nm UV light usually makes it glow golden - here you can see the glow, even in daylight 🤩. Foot for scale 😂 #Zircon #VoteZircon

Two pieces of rock sit on a carpet. One is held in position by a black leather shoe, attached to a denim-clad leg. Among the dark minerals making up these rocks, hordes of large golden-glowing zircon crystals can be seen, fluorescing thanks to 254nm UV light.

#MinCup23 kaolinite vs zircon Two beautifully-named minerals, but one is white crud, while the other sparkles and glows! Here's some zircons (up to 8mm long) from ultramafic Lewisian rocks in Iona, fluorescing golden yellow under 254nm ultraviolet light. 🥰 🤩 #VoteZircon #Geology #Zircon #Iona

A dark rock sits on a dark bluish background. Within the dark rock, large, bright golden yellow crystals glow.
