All rocks have beauty within them. You need a jeweler with experience to perform. A lapidary is someone who has the raw stone, stone, or minerals and cut and polished so that it can be added to jewelry, or simply to keep the screen. Some lapidary stone carving fanciful shapes, or representation. Other take materials like agate, onyx or fluorite and shape it into useful items like bowls, cups and plates.

For a lapidary who makes primarily cabochons (a cabochon, or cab, is flat on the back and either domed or slightly domed on top with a high gloss), it all starts with saws. Actually, everything begins with the rock. However, we are not talking about rock hounding today.

After acquiring a piece of rock that must be cut into slabs. If the piece of rock is very large, the lapidary will have to start with a slab saw. A slab saw typically consist primarily of a disk-shaped blade with a diamond wheel with coated, engine, and a deposit to hold the liquid refrigerant and lubricant. The refrigerant and lubricant may be water or oil. Water is much less complicated and usually only the commercial houses of cutting oil use. The largest bloc seen this author has ever seen is about eight feet high. This is a diamond blade drag and was built to cut large petrified logs.

Depending on the size of the finished cabochon and the material used, the slabs will be cut in different thicknesses. If the lapidary wants a very high dome over the cabochon, the plate must be quite dense. Also, softer materials produce more waste in the cutting and polishing, and therefore must begin thicker.

An oscillating saw is a smaller version of a slab saw. These are most commonly cooled and lubricated with water. If the rock is small enough, an oscillating saw can be used instead of a slab saw. Trim saw blades most often are four inches, six inches, eight inches or ten inches in diameter. A four-inch blade to cut through a rock that is less than two inches deep.

When the lapidary has the slab that she wants, first the oscillating saw is then used to cut the slab as closely to the final form as possible. Some cutters can produce calibrated shapes. These are usually drawn on the stone with a template. The most common as calibrated cabochons is oval. However, the square and round shapes are also produced.

That will be a strict set of requirements in size. This is expressed in millimeters: 12mm x 10mm, 30mm x 20mm, for example. These are meant primarily for purposes of competition. They are judged on best use of materials, size, perfection of form and Polish. Commercially available calibrated cabochons are made by the machine and the final polishing is done in a smoother fall.

This author is free form cabochons be nicer. They also present the greatest challenge to work into jewelry. You can purchase mounts Forms for calibration, but not for free-form shapes. Stands for the free forms must be manufactured from scratch. Your handmade piece of jewelry has been a lot of time invested in him by the time that has found its way to the neck or wrist.

Once the plate has been reduced to an approximate form, then begins the real fun. The lapidary then grinds and polishes the stone. This is where the lapidary's skill really shines.
