7.3" Agate "Butterfly" Wings - Brazil
This is a gorgeous Brazilian agate slice pair mounted as "butterfly wings" to create an attractive display. Each agate slice has been cut flat and polished to a glossy finish on both sides. Beautiful banding and coloration on this pair.
Including the accompanied base, the wings stand 7.3" tall. The slices are removable, and are held in place by headless hexagon screws, allowing for adjustment and preferred presentation of the agate.
Note: The agate will not be in the stand for shipment and will have to be put back in place. A hex key is not included with the specimen.

Agate is a translucent variety of microcrystalline quartz. Agate primarily forms when silica-rich fluids fill pockets within rock and/or fossils, depositing it along the walls of the rock. This process can result in banding patterns as fluid compositions and impurities change over time. These banding patterns can either form as flat layers, forming agates known as waterline agates, or as concentric layers typical of most agates, depending on the surfaces available for deposition.
Agate has also been known to fill veins or cracks in volcanic rock. Such agates, when cut transversely, exhibit a succession of parallel lines giving a banded appearance to the section. Such stones are known as banded agate, riband agate and striped agate.
Agates from Brazil are mined from decomposed volcanic ash and basalt from the late Permian age (248-275 million years old). In Rio Grande do Sul, the agate "mines" are normally just plowed fields in which loose agates are found and collected. These agates can be very colorful and polish beautifully.
