A well-chosen speed for stone polishing causes the rocks within the barrel to slide past each other, with the abrasive grit between them. The result of this depends on the coarseness of the abrasive, and the duration of the tumble. Typically, a full tumble polish from rough rock to polish takes 3–5 weeks, and is done in a minimum of 3 steps.
Lapidary tool kit from around 900 AD, Chaco Culture National Historical Park. The earliest known lapidary work likely occurred during the Stone Age. [1] [8] As people created tools from stone, they realized that some geological materials were harder than others. The next earliest documented examples of what could be considered lapidary arts ...
Vibratory tumbler with steel shots polishing small parts. Vibratory finishing is a type of mass finishing manufacturing process used to deburr, radius, descale, burnish, clean, and brighten a large number of relatively small workpieces.
Rotten stone, sometimes spelled as rottenstone, also known as tripoli, is fine powdered porous rock used as a polishing abrasive for metal smithing, historically for the grinding of optical lenses and in woodworking. It is usually weathered limestone mixed with diatomaceous, amorphous, or crystalline silica.
They appear to have been made by hammering natural boulders with other rocks, then polishing with sand. The degree of finishing and precision of working varies considerably. The gabbro came from sites in the hills, several kilometres away from where the finished spheres are found, though some unfinished spheres remain in the hills. [citation ...
Ground stone tools are usually made of basalt, rhyolite, granite, or other cryptocrystalline and igneous stones whose coarse structure makes them ideal for grinding other materials, including plants and other stones. Organic and inorganic materials are processed on ground stones into edible products. [1]

The technique used is dependent upon the level of detail required for the desired tool. The technique with the least detail is conducted using a hammerstone, in which a hard rock (often sandstone) is struck against the raw material to chip off large flakes and begin to shape the stone. Using a hammerstone produces what is called a preform ...
