G0047100 (gär′nĭt)n.1. Any of several common, widespread aluminum or calcium silicate minerals occurring in two internally isomorphic series, (Mg, Mn, Fe)₃Al₂Si₃O₁₂ and Ca₃(Cr, Al, Fe)₂Si₃O₁₂, generally crystallized, often embedded in igneous and metamorphic rocks, and colored red, brown, black, green, yellow, or white and used both as gemstones and as abrasives.2. A dark to very dark red.

[Middle English, from Old French grenate, from grenat, pomegranate-red, probably from Latin grānātum, pomegranate, from neuter of grānātus, seedy; see pomegranate.]

garnet

garnet,

name applied to a group of isomorphic minerals crystallizing in the cubic system. They are used chiefly as gems and as abrasives (as in garnet paper). The garnets are double silicates; one of the metallic elements is calcium, magnesium, ferrous iron, or manganese and the other aluminum, ferric iron, or chromium. Six varieties (of which there are also intermediate forms) are distinguished according to composition—grossularite (calcium-aluminum), pyrope (magnesium-aluminum), spessartite (manganese-aluminum), almandite (iron-aluminum), andradite (calcium-iron), and uvarovite (calcium-chromium). Grossularite occurs commonly in a red, green, yellow, or brown shade, depending on the impurities; if pure it would be colorless. The yellow and brown stones, coming chiefly from Sri Lanka, are used as gems under the names essonite (or hessonite) and cinnamon stone; sometimes they are miscalled hyacinth. Grossularite is found also in the Transvaal, in Mexico, and in Oregon. The most popular variety of garnet is the ruby-red pyrope from Bohemia, S Africa, and Arizona, sold as Cape ruby and Arizona ruby. Rhodolite, a mixture of pyrope and almandite from North Carolina, is rose-red or purple. Spessartite, a brown to brownish-red garnet from Bavaria, Sri Lanka, and parts of the United States, is seldom used for jewelry. Deep red, transparent almandite is the carbuncle; it was formerly a very popular gem. Almandites come chiefly from Brazil, India, and Sri Lanka; Australia and parts of the United States are also important sources. Andradite, a very common variety, is usually some shade of red, black, brown, yellow, or green. Gem varieties include topazolite, similar in color and transparency to topaztopaz
, aluminum silicate mineral with either hydroxyl radicals or fluorine, Al₂SiO₄(F,OH)₂, used as a gem. It is commonly colorless or some shade of pale yellow to wine-yellow; pale blue and pale green also occur, but natural red stones are

Demantoid is found in the Urals, and the other andradites come chiefly from Europe and the United States. Uvarovite, an emerald-green variety from Russia and Finland, is rarely suitable for gem use. Garnet occurs in many different kinds of rocks—grossularite, in metamorphosed impure limestones; pyrope, in basic igneous rocks; spessartite, in granite rocks; almandite, in schists and other metamorphic rocks as well as in igneous rocks; andradite, in serpentine; and uvarovite, chiefly in serpentine.

(2)A user interface development environment for Common Lispand X11 from The Garnet project team. It helps you creategraphical, interactive user interfaces.

Version 2.2 includes the following: a custom object-oriented programming system which uses a prototype-instance model.automatic constraint maintenance allowing properties ofobjects to depend on properties of other objects and beautomatically re-evaluated when the other objects change. Theconstraints can be arbitrary Lisp expressions. Built-in,high-level input event handling. Support for gesture recognition. Widgets for multi-font, multi-line,mouse-driven text editing. Optional automatic layout ofapplication data into lists, tables, trees or graphs.Automatic generation of PostScript for printing. Supportfor large-scale applications and data visualisation.

Also supplied are: two complete widget sets, one with aMotif look and feel implemented in Lisp and one with acustom look and feel. Interactive design tools for creatingparts of the interface without writing code: Gilt interfacebuilder for creating dialog boxes. Lapidary interactivetool for creating new widgets and for drawingapplication-specific objects. C32 spreadsheet system forspecifying complex constraints.
