Agate has the same chemical composition as quartz but instead of forming whole crystals, it has a microcrystalline structure. To be a true “agate,” the stone must exhibit a pattern or banding, otherwise it is considered chalcedony. Different varieties of agate include moss, tree, and lace. Much agate comes from Brazil where it is sometimes dyed vibrant colors. Other sources for beautiful agates include Oregon, Mexico, Botswana, and South Africa. Metaphysically, agate helps with emotional, physical, and intellectual balance.
An opaque variety of cryptocrystalline quartz (chalcedony), jasper is found worldwide. It owes its opacity and color to its incorporation of varying amounts of other minerals. Red to brown jasper is colored by hematite, yellow to clay, and goethite can make it brown or yellow. There are many varieties of jasper including picture, brecciated, and leopard skin. Oregon is famous for its wide varieties of picture jasper. Other deposits are found in the USA, Mexico, and Africa. Metaphysically, jasper imparts determination and courage.
Rutile-included quartz, aka rutilated quartz, features impressive needle-like crystals within quartz. Rutile is a form of titanium oxide that creates slender, prismatic crystals, both alone and as inclusions within other minerals including quartz, ruby, and sapphire. Rutile commonly ranges in color from pale golden yellow to red to brown. Most of our rutilated quartz comes from
