Welcome to the "Lapidary" Squidoo Community lens
What is lapidary?
The word lapidary is derived from the lapis or stone and means "of or pertaining to stones" or "one who cuts and polishes Stones". Not all stones are worthy of cutting and polishing and although all can be cut by one method or another the lapidary is concerned only with those stones that are capable of being polished.
The most abundant mineral in the earth's crust is quartz which is also the most common gem material. Quartz is a mineral of many names. Amethyst, citrine, smokey "topaz", agate, chalcedony, tiger eye and petrified wood are all quartz minerals and their names are derived from the color, method of formation or other characteristic.
Of these and other gem stones all but the diamond can be cut and polished with lapidary equipment, which is easily available in shops or catalogs throughout the country or by hand processes.
Essentially the lapidary process is one of shaping the material with a coarse grinding wheel or disc; then regrinding to obtain a smoother surface until a glossy surface is obtained. The polishing operation is done with various mineral oxides. Some compounds work well on one kind of stone while other compounds work on other kinds of stone.
.
Tumbling is lapidary treatment given to irregularly shaped stones by a mechanical process of continuous agitation or "tumbling" of the stones with a series of coarse to fine grits usually with water and culminating with the polishing of the baroque shapes. Tumble stones are inexpensive and are used in simple jewelry, as "feely" stones and for making novelty items such as key chains and "critters".
Among the many other types of treatment given gemstone materials the beginner usually learns first how to cut and polish a cabachon. The cabachon or for short "the cab" is a gem with a flat back, rounded or domed top. It can be round, square, rectangular, or oval in outline. Colored, opaque or patterned stone or stones displaying some interesting phenomena are usually cut as cabs. Jade, petrified wood, agate, and opal are examples of stones that are usually cut "en cabachon".
Transparent colored or colorless gemstones are most frequently faceted. This is characterized by a number of flat polished surfaces arranged in such a way that the stone reflects light which enters the stone through the polished surfaces, back to the viewer in hundreds of sparkles. The reflections may be colored as in a colored stone, white as in a clear stone, or in many hues as in a diamond or rutile. The rainbow colors are caused by light being broken up into its component colors within the stone.
Other lapidary treatments could be carving, flat surfaces assembled pieces or spheres.

I am far from being an expert with the art of bezel settings. I have just recently began participating within a forum that has a member who volunteers some tutorials and discussion for beginners like myself.
