Lapidary Art
Lapidary Art
Id like to get into the Arts lapidary, minerals, gems and rock hunting, where can I get the best educ. for both?
I live on. California, no classes, but the geology is offered. Where do I begin my learning?
Finding a school that offers the geology as a major and jewelry making as a minor? Ask if the jewelry before making cabochon cutting classes offered either as part of their curriculum. Jewelry classes should also teach not only how to set the stones but the stones are resistant to heat, hardness, definition of the Mohs scale, etc also get books to learn on their own to supplement the information. There must be some local associations lapidary / clubs and occasional meetings around hobbiests in your area. A local rock / lapidary shop should know all about.

In the gemstone world, a cabochon is a stone that is cut with a highly polished rounded or convex top with no faceting, with a flat or slightly domed base. A cabochon may be cut in any shape, though oval is by far the most common. The term comes from the French caboche, meaning knob or small dome. Certain stones are almost always cut "en cabochon," including opal, turquoise, onyx, moonstone, and star sapphire. In the gemstone world you will often hear the term cabochon shortened to "cab."
Technically, cabochons are not really "cut." Rather they are shaped and then polished. It is thus a much simpler task to produce a cabochon than it is to cut a faceted gem with many faces. Before the art of faceting was developed, all gemstones were produced as cabochons, though some were intricately carved as well.
Faceted gemstones made their appearance in European jewelry during the late 13th and early 14th centuries. With the advent of the horizontally turning cutting-wheel in the late 1400's came the possibility of designing and repeating elaborately conceived geometric faceting schemes, thereby controlling and enhancing the light coming from within the stone.
The fascination with geometry and reflected light during the Renaissance accelerated the development of a sophisticated lapidary art. Starting with the Renaissance gem-cutting trade in Bruges, to Venice, Florence and eventually the whole of Europe, the management of light became the central theme in gem cutting.
Once the technology and skill was available to facet gemstones, why were cabochons still produced? The question is an interesting one because different gems are cut as cabs for different reasons. In many cases it is because the gem has special properties that are displayed only when it is cut as a cabochon. Examples are gems that display asterism (the star effect) or chatoyancy (the cat's eye effect) or iridescence (e.g., opal) or adularescence (e.g., moonstone).
Most gems that are opaque rather than transparent are cut as cabochons rather than faceted. You will also see lower grade material in gemstones such as sapphire, ruby and garnet cut as cabs. If the gem material has very good color but is not sufficiently transparent or clean to be faceted, it can still be shaped and polished to be a very attractive cabochon. It is also common to cut softer stones as cabs, since gems with a hardness less than 7 (on the Mohs scale) can easily be scratched by the quartz in dust and grit. Minute scratches show much less on a cabochon than on a faceted stone.
