I made... Lots of things. I run out of beads sadly... More in March I guess!!!!
Variétés d'Agate, Morganite, Quartz, Hématite, Opalite... I'm trying to get back on tracks with simple yet enjoyable things 🥰

A #Macro view of a #quartz #crystal spar, jutting out from the main body of the crystal matrix.
Quartz is crystalline silicon dioxide and comes in many colors caused by inclusions of other elements or contaminants.

Currently a competitor in #MinCup23, #Quartz is a #crystalline form of silicon dioxide (#SiO2) with a trigonal #crystal system that, ideally, results in the growth of a hexagonal column with pointed ends, but nature rarely allows this, as this #Macro #image demonstrates.

#Quartz is a #crystal form of #SiliconDioxide (#SiO2) in a trigonal crystal system.
Other #mineral forms of silicon dioxide exist, but quartz is probably one of the most common.
Other things can be included into the crystal, or the crystal structure can be deformed, both of which are forms of #flaws in the crystal.

A piece of blue #quartz, a type of quartz whose #blue #color is often a result of inclusions of sodium or different #silicate #minerals in the crystal, possibly with a small amount of iron.
The crustal is sitting on a light table.
