Al2O 3 (aluminum oxide) One is the metamorphosis of limestone and the other is an igneous occurrence in rocks lacking in silica. Since corundum is so hard it is very resistant to weathering. the United States. Although the finest precious gems occur in foreign countries, a wide variety of semiprecious stones, and a few precious gems, have been found in the United States. About 50 major gems and the geology of their occurrence are described in this .

      Primary corundum deposits are subdivided into two types based on their geological environment of formation: (1) magmatic and (2) metamorphic. Magmatic deposits include gem corundum in alkali basalts as in eastern Australia, and sapphire in lamprophyre and syenite as in Montana (United States) and Garba Tula (Kenya), respectively. NEW. Glossy cover, pages are acid-free. This beautifully illustrated book is a depiction of one of the most comprehensive collections of sagenite, plume, and banded agate in the world. More than high-quality photographs of beautiful and rare agates from 20 countries and 19 U.S. states (more than separate agate deposits are covered).

Corundum is found as a primary mineral in igneous rocks such as syenite, nepheline syenite, and of the world's most important ruby and sapphire deposits are found where the gems have weathered from basalt flows and are now found in the downslope soils and sediments.

Corundum is also found in metamorphic rocks in locations where aluminous shales. CORUNDUM, a mineral composed of native alumina (Al 2 O 3). remarkable for its hardness, and forming in its finer varieties a valuable gem-stone.

Specimens were sent from India to England in the 18th century, and were described in by the Hon. Greville under the name of corundum—a word which he believed to be the native name of the stone (Hindi, kurund; Tamil, kurundam; Sanskrit.
