Captivating Cameos


QUESTION: A few years ago, I went on a trip to Italy. While traveling along the Amalfi Coast south of Rome on my way to visit the ruins of Pompeii, I discovered shop after shop filled with beautiful cameos. I bought several and would love to buy more. What can you tell me about the origins of cameos, and how can I tell if cameos are genuine? 

ANSWER: Cameos have been collectible since the Renaissance in the 15th century when wealthy women collected them as status symbols. Today, elderly Italian master carvers are retiring, causing an escalation in the prices for finely carved cameos. Plus, new laser-cut cameos from China have been flooding the market. It’s now a buyer-beware market where only an expert is able to discern a really good cameo.

A cameo is a form of carved bas-relief, which features portraits, landscapes, and mythological figures cut into a variety of materials, but most often into gemstones and shells. Artisans, both ancient and modern, have crafted cameos from two layers of one piece of material, the top of which protrudes from the background, creating a multi-dimensional artwork. Throughout history, these detailed reliefs have adorned pieces of jewelry, such as brooches, necklaces, bracelets, and rings. But the earliest cameo carvers took their inspiration from prehistoric petroglyphs, which documented important religious and symbolic imagery onto rock faces.

Cameos first appeared as far back as 15,000 BCE. where ancient Egyptian civilizations carved figures into rocks to record important events. Cameo artistry traveled between the ancient Mediterranean cultures through trade routes connecting Egypt, Greece, and Rome, and often depicted mythological themes while paying tribute to gods and goddesses. As the Roman Empire grew, cameo carvers began to incorporate political portraits into their pieces. Wealthy people could afford to buy the expensive gemstone cameos, while less wealthy ones bought glass cameos.

During the reign of Alexander the Great in the 3rd century B.C.E., Greek and Roman cameos incorporated religious figures and mythological images. Also during this time, specifically in the Hellenistic era, women wore cameos to display their willingness to engage in the act of lovemaking. By the 15th century, cameos produced in Italy began to differ from the ancient ones.

In the 18th century, wealthier women began wearing impressively carved gemstone cameos as a sign of wealth and prestige. Carvers soon realized they could use Plaster of Paris molds to recreate cameos from notable collections. Scottish gem engraver and modeler James Tassie began using molds of these famous cameos to recreate glass pastes that could pass as authentic, carved jewels.

Carvers realized just how easily they could replicate expensive jewels. They discovered the use of Cornelian shells, which were soft, durable, and easy to carve. Queen Victoria popularized shelled cameos, featuring natural and humanistic scenes carved onto deep-sea shells. Meanwhile, as interest in collecting cameos grew, French military leader Napoleon  He brought carvers from all over Europe into France to create cameo jewelry for both men and women. He even commissioned furniture to be designed with cameos carved out of precious gemstones like opal, sapphire, and garnet.

A new type of cameo made from lava rock also appeared during this time. Colored lava extracted from an archaeological dig at Pompeii proved useful for highly detailed carvings. Women often purchased lava cameos as mementos from their travels on their Grand Tours, which established the objects as a symbol of status and wealth.

Over the centuries, artisans have created cameos by carving figures in bas relief from precious gemstones such as onyx or agate, one of the most commonly used. The most common motif of antique cameo jewelry depicted a profile of a face or mythical creature. Whether ancient or modern, cameos typically have two colored layers—figures  carved in one layer raised on the background of the second layer. Today, workers in “cameo factories” carve cheap imitations in paste glass or in seashells. The best shells come from the coast of Africa. The shell, itself, has no value. It’s the quality of the carving that gives a shell cameo value.

The rareness of a cameo outweighs its age when determining its value. For example, though the Roman Empire predated the Renaissance era, experts consider Renaissance cameos more valuable as there were fewer produced back then.

It’s important to examine a cameo by holding it up to a light to ensure there are no major cracks. Those that have three or four layers of color and a metamorphic image, which includes several subjects, are particularly valuable. Further, colored stones like opal, lapis, and emerald are rare, so they’re even more expensive.

When purchasing a cameo, it’s necessary to use a magnifying glass to look on the inside of the rim of the setting for the gold value and for sharper cuts or fewer details. A signature makes it more valuable, but collectors seek some signatures more than others. Unfortunately, it takes an expert to find the signature of a laser-cut cameo. It’s easy for a novice collector to be fooled into buying them at greatly inflated prices.

Two sought-after designs are “The Three Graces,” a scene of three full figures in flowing garb. The other is “Rebecca at the Well,” a theme that usually includes a full figure of a woman, a cottage or a well, and often a bridge. Both are late 19th-century favorites.

Cameos made of gemstones are generally more valuable than those made of shell. But the medium isn’t as important as the quality of the carving.  Graceful, smooth-flowing lines with much detail are signs of a good one. The inferior ones seem to have sharper lines, fewer details, and a harsh look.

Scenic cameos, on the other hand, are generally pricier than bust cameos. A very popular motif around 1860 was what is known as ‘Rebecca at the Well.’ There are many variations on this theme, but they usually include a cottage, a bridge, and a girl.

Prices for cameos continue to rise, making them a good investment. One with a small bust or portrait might sell for $30 to $400 if well carved. Prices for larger scenes and unusual themes or with sought-after signatures may begin at $500 or $600 and go up from there.

Collectors often find smaller cameos at antique shows or shops for $100 to $150. But for those prices, experienced collectors don’t expect top quality. These cameos may be less expensive for several reasons. First, they usually have less detailed settings. Second, they’re usually smaller and unsigned. And third, they have been carved more recently and less artistically.

Slow and Steady Wins the Race



QUESTION: I like antique clocks and have a number of them in my home. I saw this English, tortoiseshell carriage clock sold by J.C. Vickery of London in 1904 at an antique show recently but was hesitant to buy it because tortoiseshell is now illegal. Can I still purchase this clock or will I be committing an illegal act? Also, what can you tell me about tortoiseshell decoration?

ANSWER: While it’s illegal to use tortoiseshell in manufacturing items, it is legal to buy and sell antiques in which tortoiseshell has been used as a decoration.

Tortoiseshell is an ornamental material obtained from the curved horny shields forming the shell of the hawksbill turtle. People have long valued tortoiseshell’s marbled, varicolored pattern and deep translucence for making jewelry, furniture, and other objects. The Romans first imported it from Egypt. During the 17th-century, the French raised the level of artistry for tortoiseshell in decorating jewel cases, trays, snuffboxes, and other items. The craft soon spread to other parts of Europe.

Eastern and Western artisans used tortoiseshell from ancient times until the buying and selling of raw tortoiseshell was banned in 1973 under CITES, the Convention on International Trade in Endangered Species. Ancient Greeks used tortoiseshell to make their lyres and wealthy  Romans used inlaid veneers of tortoiseshell for furniture, especially couches for dining, and for small objects.




Craftsmen normally used it in thin slices or pieces to make a wide variety of objects such as combs, small boxes and frames and inlays in furniture. Despite its high price, manufacturers and consumers favored it because of its beautiful mottled appearance, its durability, and its organic warmth against the skin.

The French perfected the use of tortoiseshell on furniture by completely covering pieces with sheets of tortoiseshell and brass cut into intricate patterns that fit into one another, the tortoiseshell alternately forming the pattern and the ground, resulting in two types, boulle and counterboulle. André Charles Boulle, cabinetmaker to Louis XIV of France for whom this style of decoration is named, introduced and perfected marquetry combining thin inlays of tortoiseshell backed with metal or with woods and metal.




Another decorative technique, usually employed on tortoiseshell, was piqué work, in which artisans created inlaid designs using small gold or silver pins. The art reached its highest point in 17th- and 18th-century France, particularly for the decoration of smaller articles such as combs, match boxes, and snuffboxes.

To prepare tortoiseshell for decorative use, craftsmen would first separate it from the tortoise’s  bony skeleton by heat. They would then flatten the shields by softening them in warm salt water and flattening them using a press. finally rasping away any irregularities. Tortoiseshell can be easily worked using heat and pressure and can be shaped on a lathe. Two pieces could be fused by use of a hot iron, but like the earlier stages, craftsmen had to be careful not to lose the color. When a craftsman completed a piece, he would polish it using various techniques.

Victorians who wished to show off their wealth would prominently display tortoiseshell items in their homes. They enjoyed tortoiseshell boxes and containers as much for their decorative quality as for their storage possibilities. During the Victorian era, artisans embellished tortoiseshell jewelry with precious stones and gold and silver. They even hand carved some pieces.

Those who collect items made with tortoiseshell must be able to differentiate between the real thing and fake or faux tortoiseshell. But it takes an experienced eye to easily tell the difference. Generally, real tortoise shell is lighter than fake examples, and when compared, the former would have more depth and layers, which is part of the reason why it’s favored for use in jewelry making.

To help distinguish real tortoiseshell from faux tortoiseshell, collectors often use a pin test. However, the person selling a tortoiseshell item might not be too keen on having someone using a hot pin or a piece of sandpaper to see whether it will smell like burned hair since markings or spots may be left on the shell afterwards. Believe it or not, faux tortoiseshell smells more like burned hair than the real thing.

Collecting real antique tortoiseshell objects and jewelry can be expensive since these items are becoming increasingly rare.

Romancing the Road



QUESTION: My mother saved every map she and my dad collected on their many road trips. Some of these go back as far as just after World War II.  Do these have any value today?

ANSWER: Road maps, especially the ones produced by oil companies for their service stations, are highly collectible. While older ones can be worth higher amounts, depending on their condition, newer ones aren’t as pricey. They’re also easy to store, so a collection won’t take up a lot of room—always a good thing for those living in apartments.

The systematic mapping of roads and the installation of route signs by the government didn’t occur until the auto arrived. Prior to the mid-1890s, bicyclists were the ones who demanded road maps. But as the new century dawned, the number of automobiles on the roads began to increase. The Chicago Times-Herald printed the first automobile road map in the country for a race they sponsored from Chicago to Waukegan.

In 1918, Wisconsin’s state legislature initiated a numbered highway system., which the federal government adopted in 1926. The new highway system gave us the names for legendary roads like Route 66 or California’s scenic Highway 1. Rand McNally became the first major publisher to adopt the system, which it also helped promote by installing numbered signs along these national roadways.

Before World War II, service stations gave out road maps free. These featured elaborate artwork. Oil producers such as Esso, Chevron, Shell, Gulf, Standard, Texaco, and Socony-Vacuum (later known as Mobil) all distributed maps.

Raod maps belong to the growing category of collectibles called “petroliana,” or anything to do with gas stations and the petroleum industry. For the most part, they’re reasonably priced, and some estimate that during their peak service stations distributed over 8 billion. Oil companies provided them as a service. They were made to be disposable, marked up by the gas station attendant as he gave directions and sent his customer on their way. But people often saved maps as souvenirs of the trips they made.

As automobiles proliferated, the marking of routes changed. Before numbered roads, stripes of paint on telephone poles, fence posts or trees delineated the various routes. In 1925, states began numbering their roads. At first it was an adventure to drive, but by the 1930s it had turned into a method of tourism. Tourist cabins sprang up along the way, as motorists made their way across country. Historians consider this time the road map’s golden age.

The Sinclair Oil Company hired noted artists like Peter Helck, who also produced advertising illustrations for car companies. Maps featured images of a carefree and playful life on the road, with service stations welcoming children and dogs, many of which were Scottish terriers, like the ones popular in movies like “The Thin Man.”

Maps produced during World War II reminded motorists to slow down to save tires. After the War, maps featured dynamic scenes, vibrant colors, and great graphics.


By the baby booming 1950s, the images tended to show nuclear families—a mom, dad, son and daughter, all enjoying life on the road. During the 1960s, maps displayed the dotted lines of planned Interstates and aerial views of highway cloverleafs.

Three companies—Rand McNally, H. M. Gousha, and General Drafting—produced most of the service station maps. These became a vehicle through which oil companies could promote the service at their stations, for it was service that differentiated them.

General Drafting produced maps for Esso, whose attendants handed out some 34.5 million maps in 1965.
After 1965, the quality of service station maps declined until their virtual disappearance in the 1980s.

Today, of course, free maps are long gone. They faded away, along with so many other aspects of the highway culture, with the 1973 energy crisis.

Early road maps from the first decade of the 1900s can be worth $75-100 today in good condition. Those from the 1920s and 1930s range in price from $20-40.  Groups of maps from the 1950s sell for $10-20.
