This is a never-ever described compound right after recrystallization(:
This is some unspecified organic compound, those crystals look big enough to get a few pretty slammin’ diffraction patterns to get an atomic structure. Congratulations!

The Fukang Meteorite
Back in the year 2000, an incredible meteorite weighing 2,211 pounds was discovered near Fukang, a city located in the northwestern region of Xinjiang, China. Named the Funkang meteorite, it was identified as a pallasite, a type of stony–iron meteorite. With 4.5 billion years in the making, its golden olivine mixed with silvery nickel-iron to create a stunningly beautiful mosaic effect.
Pallasites are extremely rare even among meteorites (only about 1% of all meteorites are this type) and Fukang has been hailed as one of the greatest meteorite discoveries of the 21st century.
It has since been divided into slices which give the effect of stained glass when the sun shines through them. It is so valuable that even tiny chunks sell in the region for $40 to $60 a gram. An anonymous collector holds the largest portion, which weighs 925 pounds.
WHO ELSE MISREAD THIS AS “THE FUCKING METEORITE”
God fukang dammit

The pink variety of spodumene is called kunzite. It’s bright color comes from manganese dopants. Manganese ions are likewise responsible for the permanganate ion, common as part of a basic solution that you probably have (or will) use in chemistry class.

The anisotropy, or directional asymmetry, of epidote causes the stone to appear different colors from different directions. The crystal structure bends light differently depending on the path, appearing to you as a color change.
This picture shows a bluish-green for the crystals on the left, and a more yellow-green on the right.

Smoky quartz gets its black or, in this case, brown color from elemental silicon suspended in the SiO2 crystals. The elemental silicon is formed when the stone is exposed to radiation, either natural or man-made.

A copper (II) tetraphenylporphyrin complex.
There’s a lot of beautiful minerals on this site, but as a chemist, I spend more time looking at small crystals like this. In chemistry, growing crystals is really important for understanding the material you’ve made. Crystallinity opens up the door to powerful characterization techniques like X-ray diffraction.
Plus, it is really pretty.

Euclase- Named after the Greek word “euklas”, in French “euclase”, meaning “to break”.
Facilitates benevolence, selflessness, generosity and altruism. It is also a wonderful crystal for improving communication skills.It connects one to the source of joy within one’s self. Clear gemstones of Euclase can be cut and set in jewelry it is better known as a collectors’ item. Euclase helps one reach for goals and attain the ultimate in any area.

Vivianite, Fe3(PO4)2 · 8(H2O)
This lovely green color may turn black eventually. Vivianite darkens when exposed to light because the iron 2+ ion undergoes a transition which turns the crystal opaque.

The Fukang Meteorite.
This piece shows off the meteorite’s characteristic large pieces of peridot ((Mg,Fe)2SiO4) suspended in a metallic nickel-iron matrix.

Apophyllite is named for its notable destruction on heating; the heat evaporates the water from the chemical formula (the H2O after the dot) and causes the mineral to flake away.
