Cutting and polishing
In the manufactacturing process, the term "colored stone" refers to gems with the exception of diamonds. The cutting of the colored stone is  called lapidary work; the cutter is known as a lapidary. Most lapidarys specialize in a certain gem or stone group, so that consideration can be best given to the characteristics of the stone, such  as depth of color, pleochroism, or hardness. Circular saws with edges containind diamond powder instead of teeth are used first to cut the stone roughly shaped, are  and required size. The final shape is given to the rough stone on a vertical, roughly grained carborundum wheel, cooled with water. Opaque stones, or those with inclusions, are cut in cabochon on a grooved carborundum or diamond wheel. Transparent stones, once roughly shaped, are faceted on horizontal grinding wheels. for this purpose, they are cemented with a special cement, wax or shellac on one end of a small 4-6 in 10-15cm long holder called a dop stick . these dop sticks are holder in the appropriate hole of faceting machine and set the angles to the grinding wheel. Instead of such a board a holder with a faceting head is used by the lapidary to adjust the angles. The substance from which the cutting wheel was made (lead bronze copper tin) and the type of polishing powder (carborundum diamond titanium carbide and oxides) as well as the speed of the wheel, varies with the stone to be worked.
