Agate is a microcrystalline variety of silica, chiefly Chalcedony, characterised by its fineness of grain and brightness of color. Although Agates may be found in various kinds of rock, they are classically associated with volcanic rocks and can be common in certain metamorphic rocks. Colorful Agates and other Chalcedonies were obtained over 3,000 years ago from the Achates River, now called Dirillo, in Sicily. Most Agates occur as nodules in volcanic rocks or ancient lavas where they represent cavities originally produced by the disengagement of volatiles in the molten mass which were then filled, wholly or partially, by siliceous matter deposited in regular layers upon the walls. Such Agates, when cut transversely, exhibit a succession of parallel lines, often of extreme tenuity, giving a banded appearance to the section. Some Agates are found to be translucent when cut thin enough. Many different varieties and types of Agate occur naturally and all different kinds of names have been applied based on location found or the colors in the Agate. Moss Agate is one of some 130 plus names currently associated with specifically named Agates.
Cloisonné is an ancient technique for decorating metalework objects, but in recent centuries using vitreous enamels, and also inlays of cut gemstones, glass, and even linen. and other cloth materials, has become common place, especially in jewelry beads.
Ivoryite is a great substitute for ivory. It is a sedimentary precipitate of magnesium, calcium and silica. It is 5 to 5-1/2 on the Moh's scale, which makes it slightly harder than ivory. Ivoryite can be worked with metal tools, but cuts effortlessly with diamond tools. Polishes well with diamond, tin oxide, cerium oxide or white rouge. Excellent material for inlay, cabochons and small carvings. Do not confuse Ivoryite with Ivorite, whic is a black tektite material from Africa. The majority of Ivoryite currenly comes from the western United States, especially Colorado and California.
