What many collectors don’t know is that Brazilian agate is a form of chalcedony, which is a cryptocrystalline form of silica.  This type of specimen consists of very fine grains of quartz and moganite minerals, both of which are forms of silica. Quartz is a trigonal crystal structure, while moganite is monoclinic.  The waxy luster of chalcedony can be either translucent or semitransparent.  Brazilian agate is less transparent, but it can be exceptionally iridescent when light shines through it.  Most agate is multi-colored, with bands of curved or angular contrasting shades

Other forms of chalcedony that are popular among rock collectors include aventurine, cornelian, mtorolite and onyx.  Each of these groups includes a wide variety of specimens that are often found in retail rock shops.
