Originally, and still in discussing historical work, cameo only referred to works where the relief image was of a contrasting colour to the background; this was achieved by carefully carving a piece of material with a flat plane where two contrasting colours met, removing all the first colour except for the image to leave a contrasting background.

Today the term may be used very loosely for objects with no colour contrast, and other, metaphorical, terms have developed, such as cameo appearance

Cameo subjects

Classically the designs carved onto cameo stones were either scenes of Greek or Roman mythology or portraits of rulers or important dignitaries. In history, agate portrait cameos were often gifts from royalty to their subjects. These antique cameos, some more than 2000 years old, are either displayed in museums or are in private collections.

Payne challenged Pistrucci to carve a copy to prove his claim. The ensuing publicity earned Pistrucci several commissions.

Modern cameos

Many modern cameos are carved into layered agates. The layers are dyed to create strong color contrasts. The most usual colors used for two layer stones are white on black, white on blue, and white on red-brown. Three layer stones are sometimes made. The colors are usually black on white on black. The layers are translucent, this allows the artist to create shading effects by removing material to allow the background layer to show through. This way a very realistic, life-like quality to a figure can be achieved. For example thinning the top black layer on a three layer stone changes its color to shades of brown. Removing material from the white layer creates shades of blue or grey depending on the color of the base.

Ultrasonic machine carved cameos

The majority of modern agate cameos are carved with the aid of the Ultrasonic Mill. This is a process where multiple copies of a master design can be produced very quickly by pressing a master die onto the agate cameo blank. A film of diamond slurry is used to aid cutting and the die vibrates ultrasonically in a vertical motion. The master is often hand carved by a skilled cameo artist.
The result is a cameo that has a satin surface texture described as "freshly fallen snow", (FSS) by Anna Miller. This texture and the lack of any undercutting are used by appraisers as markers to prove that the cameo is machine-made.

Hand-worked portrait cameos

These cameos are carved by hand usually working from photographs of the subject. The fact that there is usually only one copy made means that the tooling costs involved rule out the ultrasonic carving process.

There are very few people working in this field as this is one of the hardest challenges for any gemstone carver. The combination of a highly developed artistic ability, craft skill and many years of experience are needed to be able to create life-like portraits.

It is quite rare, these days, for subjects other than portraits to be carved by hand as agate cameos. The traditional themes of classical scenes from mythology or a standard image of a young lady, are more likely to be made with the help of the ultrasonic carving machine as a limited collection of typically 50 – 200 pieces.

The actual cameo is mainly cut with a metal scraping tool called a bulino, an invention of Jewish artisan Antonio Cimeniello. A number of metal gravers are used: flat-faced, round and three-cornered. To speed production, grinding wheels are used to quickly remove excess material. When the details are completed, the shell is then soaked in olive oil, cleaned with soap and water and selectively polished with a hand brush.
