Diving off the coast of Madagascar for a cameo performance

Carnelian Shell in its natural habitat Diving in the shallow waters off of the African coast, one could at one time find a wealth of colorful tropical fish like the Picasso Trigger fish or Cypraecassis rufa. But that last name will probably not stick out to unless you put it into a more familiar context.

It is also better known as a bull mouth helmet or a Carnelian (sometimes written cornelian) Shell.  Besides being sought after for its natural beauty, this shell has become a favorite for the carving of cameo brooches, pendants and earrings. The latin name might not make it sound as elegant as the end results, but Italian artisans have been carving them into beautiful objects since about the early 1800′s.

Curious but true – this hard substance is actually a snail shell! Found off the southern African coast, this sea snail is common in Mozambique, the shores of Kenya and Madagascar. Not only is the strong and durable shell noted for its presence in cameo jewelry art, but for this very reason (high resistance) this group of shells are also well represented in the fossil records. Described as having a conspicuous, solid, thick, heavy shell, up to 17 cm, once can find it has a dorsally reddish color with broad spiral bands bearing rounded nodules. Thick outer lip in light orange and accents of orange with white ridges.

Carnelian or Cornelian Shell Cameo with 18K yellow goldThese shells are not only attractive to the jewellery market for their striking colors and durability but also because they naturally lend themselves to the art of cameos. A cameo nearly always features a relief image with a contrasting color negative image. The composition of this shell with the various layers makes it ideal for using the art of intaglio to carve out images of beautiful women, Greek and Roman gods as well as rulers and kings.

A cameo is a relief image with a negative image in a contrasting colorActually it wasn’t until the 18th century that cameos were made of shells – normally the Renaissance cameos came from hardstone, mussel or cowry shells – however they all provided that distinctive dark background to the white or whitish relief image. Then with world exploration – and unfortunately exploitation, cassis tuberosa from the West Indies became the raw material of choice when making cameos.

There is a downside to the over harvesting of shells – and actually any type of exotic fish from these natural beautiful waters. After years of emptying the African coast of this elegant and important creature, places like Kuruwitu are only just beginning to re-establish a balance in their oceans. Beautiful Helmet Shells like this one have been removed from the coastal waters in their hundreds of thousands to sell to tourists. It’s role as an important predator of sea urchins made it a fundamental element to the survival of the eco-system.

Beautiful sea Snail, also called bull mouth helmet shellSince these creatures feed on sea urchins their removal from their natural habitat in mass quantities resulted that sea urchins proliferate uncontrollably killing off coral reefs and destroying the natrual environment. Which explains why areas like Kurumai have worked hard to protect their shore lines. We encourage you to read about the work being done to save the environment off of Kenya.  We also encourage you to buy your cameo from a reputable vendor who will document that the shell has been harvested according to all international regulations.

The Art of Hand Carved Cameos

Blue Agate Cameo

The technique of hand carving cameos is an artform that goes back hundreds of years. These beauties were once used for a number of purposes from recording history and heroes to displaying ones social and/or cultural status. Today, Naples, Italy specializes in this workmanship, carving countless cameos that are sent all around the world.

Carved from several types of material in an array of colors, most pieces can be worn as a necklace or brooch, making for a well-rounded piece of jewelry. In my opinon, there is something particularly special about cameos. Not only do they carry an everchanging story throughout the world’s history but they have versitilty in wear and style. I myself have one that I usually style as a vintage piece of jewelry but it can just as easily be worn as the traditional, elegant piece it is.

Typically, cameos are carved from a few different types of shell:

Carnelian Shell – This is the most commonly used shell usually light peach or orange in color and also my personal favorite

Sardoynx Shell – Resembling marble, this shell has a thicker outter layer and a dark brown interior

Mother of Pearl – Once carved this material creates a blue, gray translucent color

Agate – Slightly different from the rest, agate is a stone found in various types of rock that’s generally blue or green

Just take a look for youself! You can literally find just about anything carved into these works of art now a days, from The David to your pet cat, Whiskers.
