Agate Slice
Agate Slice
Item #119
Agates are rocks consisting of microcrystalline quartz called chalcedony. They are typically formed in pockets within cooled lava. As water flows through the lava, the pores in the cavities - called vesicles - act as tiny filters which catch silica particles that were in the water. As these particles accumulate, various silica based minerals can be deposited to create colorful bands in the rock which can be seen whenever the rock is cut open.

Very pretty and a great size
I love that every item comes with the information cards explaining a bit of its history/qualities. Fun gift for my scientifically-inclined partner.
