Cabbing Jade Cabochons.
Cabbing gemstones was the usual method to handle the "pretty little things" until about two hundred years ago when new technology which became available to cut and polish precious stones. Since precious stones are mostly inorganic minerals and some of the hardest elements in the world it again needed special material to handle them.
It took them until resent time to invent them via new technologies. Cabochon cutting or cabbing is the most popular form to treat gems not only with jadeite jade also often used with ruby stones plus sapphires (corundum) and other. Actually almost all gemstones which are not clear enough for faceting and promising enough fire are used in one way or another as cabochons. Spinels are often categorized wrong sometimes people taking them as rubies corundum and similar cab.

Modern fashion and style needs jade cabochons and beads and often balls for chains.
One of the oldest methods of cutting gemstones is the rounded shape known as the cabochon. This is a French term which itself was derived from the Latin cabo meaning head. Cabochon-cut jade & rubies and sapphires generally fall into two categories: stones which are too heavily included to be faceted and star stones.
The cabochon may be cut in a number of ways. Domes vary from very low almost flat surfaces to very high steeply curved surfaces. Usually a medium to high dome is preferable. With transparent gems, the back of the cabochon is generally flat or slightly convex and polished. Convex polished bases are used to provide greater brilliance in stones which possess enough transparency. However, should the stone be near or completely opaque a flat base is considered more desirable, as there is no excess weight below the girdle.
In any case jade is one of the minerals heavy used as a natural source for cabochons since plenty of colors are available and because of modern manufacturing machinery the handling poses no more problems as it was the case until the 19. Century because of the hardness of the jade stone.
Excess weight below the girdle should not exceed about 20% of the whole stone, for it must be remembered that the stone is being paid for by weight. Occasionally stones from Burma, India and Sri Lanka are seen with such heavy bottoms that they look like bowling balls. Just as with faceted gems, these bottom-heavy stones should be valued at the weight they would be after re-cutting to perfect proportions. Overly dark material is sometimes cut as 'hollow' cabochons, with the base being concave to lighten the
Jade was one of the first creative materials to be used since Chinese craftsman already tried for long time to be creative with nephrite they even used the "stone of heaven" for medical purpose.
Although many cabochons used nowadays are made of plastic nothing beats a beautiful jade creation in various colors forms and frame material where jade jadeite the preferred material is silver since the cool appearance of jade stone and silver give a perfect match, it is also not as expensive as gold and platinum . It needs to mention that there is no real carving involve the stone is always formed by drilling. Today also the tools are available to make pretty and flawless polishing and faceting of cabochons available but there is still the opaque structure of the stone and this cant be changed only by synthetic means but who likes that? . Anyway currently almost all jade-stone novelties are made from jadeite although nephrite still has its place in the cheaper fashion industry.
