Reversible Opal Cameo

A special gift for a wedding. The front has a portrait of the bride and groom carved into precious Opal. Pinned onto Lapis Lazuli.

Opal & Lapis Lazuli Cameo

A swivel joint allows the stone to be turned over to show the back. Here is a cameo of the mother and father from their wedding day.

Opal Cameo Jewelry

Opal is a beautiful stone for a cameo. The portrait details are more subtle than Agate, due to Opals softness. The play of color adds a special beauty to the Jewel. Carving Opal is a delicate process and great experience is required.

Cameo Portrait of a Daughter in Precious Opal

The original precious Opal is shown on the left.  This was supplied by Just Opal and was found in CooperPedy, Australia.  As this was a crystal Opal I made a black onyx slice to back the stone. This enhances the color and makes the portrait more prominent. The play of color in a fine Opal gives a wonderful effect, especially as the gemstone is turned, as this changes with movement. The dual purpose setting is in Gold and can be worn as a brooch pin or a pendant. The stars engraved around the carving  are a tribute to her sports team's logo. The reverse is engraved with a personal message and a posy of flowers.

Portrait Cameo Carving in Opal

Precious Australian Opal. This is carved with a portrait of a young wife. This was a difficult carving as the play of color layer was quite thin. I had about the depth of a coin to carve her profile.


Opal Cameo Necklace

This Antique Opal cameo jewel works so well. The portrait is cut to the profile and enhanced with Diamond and Gold detailing. The Opal is backed by a red enameled 'Guilloche' or engine turned gold plate. A delicate surround of entwinned scrolls with Diamond accents completes the jewel.

Opal Dress Ring

A cocktail ring by Gareth Eckley, with a large Crystal Opal from Australia. Set in a ring designed to echo the ocean. Yellow and White Gold waves cradle the Opal. The gem is accented with Diamonds.

Opals Suitable for Cameos

A stable stone, free from cracks and with a thick layer of fire is needed for a good carving. Ethiopian Opals have a higher water content than others, this makes them less stable.  Brazilian and Australian Opal are the best sources for Opal for carving. Opal is a soft stone and does not like heat or pressure. The carver has to have a light and delicate touch to avoid damage. Opal carvings must be polished. This makes carving Opal a long process and great experience is needed to create the best results.  The Black Opal from Lightening Ridge or Mintabe is so rare in large sizes that a cameo sized stone could cost more than $100,000.

The most highly prized is Cherry Opal from Mexico, which sometimes has a play of color. Honduran Opal has a black base and there are some very good gemstones found there. Green, Blue, and Pink Opal with a strong body color is great for carving and cut stones. Peruvian Opal is also known as Andean Opal as it is found in the Andes mountain range.

The cameo on the left is a darker Australian Opal and is set in a gold ring.

Australian Opal Locations

The finest Opal in the world is found in Australia. Lightning Ridge, in New South Wales, is famous for Black Opal, the play of color is displayed on black. Grawin, Mintabie, and Andamooka can also produce Black Opal. White Opal, with the play of color on a white background, is found in Cooper Pedy and White Cliffs. Crystal Opal has the play of color in a transparent material. This is found in many localities. Boulder opal has a thin layer of precious Opal on a layer of ironstone. The Yowah nut is a nodule of ironstone that can be split open to reveal opal patterns inside. This is only found at Yowah in Australia.

Brazilian Opal

Brazilian opals are rare and have been unavailable on the international market for many years. Brazilian opals are the oldest and hardest Opals known. They formed 60 million years ago, during the Cretaceous period. The hardness is 7.0 on the Mohs scale. They have less water than other varieties and are more resistant to cracking.

Australian opal miners explored Brazil in the 70s and 80s, and mined all of the Opal that they could find. They taught Brazilian miners the art of prospecting, mining, and polishing opals.

There is a new generation of Brazilian opal miners. A company that respects commercial and environmental, values. They sell beautiful Brazilian opals, directly from their mines in Pedro, Brazil.

Ethiopian Opal

Crystal Opal with a great play of color is mined in Ethiopia, also known as Welo Opal. Large sizes are available and this is a very striking stone. This Hydrophane Opal has a high water content due to its young age.

The first Ethiopian Opals had many issues with cracks and fractures. The Opals now found are mined from deeper underground and are far more stable.

This Opal presents a problem for the gems carver. Opal has to be tested for stability. Immersing in water can reveal cracks before carving. However, even after taking precautions, I could spend many hours carving an Ethiopian opal only to find that it cracks after I have finished. I cannot take that risk with a customer so I do not work on Ethiopian opal.

Pineapple Opal and Fossilized Opal, Shells, Belemnites, Wood, Teeth, and Plants.

Opal starts as a solution of silica in water forming within cavities within rocks. If the silica fills in space left by plants, shells, or bones the Silica can produce an opal cast of the original object. If the conditions are right for precious opal formation then the fossil can become opalized but this is rare.

Pineapple Fossil specimens are not real Pineapple fossils but the result of a rare combination of Glauberite and other chemicals that form this specimen that resembles a pineapple.

It is estimated there are less than 500 opalized Pineapples in the world. The only place on earth where these are formed is at White Cliffs, South Australia in a small opal field.

Antique 19th Century Boulder Opal Cameo Pin

An unusual technique where the matrix, or the ironstone rock under the Opal, becomes part of the design. This matrix is usually cut away or left hidden. The precious Opal layer is carved with a winged helmet. The face and reverse is carved into the ironstone. This gives a very strong contrast. Believed to have been carved by William Schmidt, this sold for $17,497 in 2015.
