About Opal
What is an Opal?
National Gemstone of Australia
'Play of Colour’ is a unique visual phenomenon which sets precious Opal apart from all other gemstones. An Opal may display one or more, and sometimes all of the 7 spectral colours. The colours are seen within the grains of a pattern. As the stone is viewed under different lighting conditions or from different directions, the colours of each grain may change as may its shape, revealing a lively moving pattern.
Three Varieties of Natural Australian Opal
Each variety is a classification determined by background or body colour and may include several types as outlined.
|
White Opal has a body tone ranging from milky white to translucent. Found at most fields but mainly at Coober Pedy and in South Australia. Crystal Opal tends to be transparent with bright colour flashes suspended in its midst. White Opal, with its lighter to whitish body colour, gives the full colour array in a more opaque background. |
The Formation of Opal
Around 100 million years ago when dinosaurs roamed the earth....

..unique geological and climatic phenomena began in what are now
Australia's desert regions, making it home to 95% of the world's Opal supply.
Spiritual Healing with Opal
Metaphysical Properties & Awareness
Many civilizations, cultures, and peoples have used crystals, stones, and minerals for healing and protection, not only of humans, but also for their animals and their environment.
The ancients believed that if a person wore the precious stone which, according to their tradition, was in affinity with the planets and the month of their birth, they would have protection against their enemies, sickness, accident, or even death.
In Medieval times Opal was thought to ward off illness and it was believed could confer the power of invisibility.
Modern Spiritual Interpretation
Opal is an emotional balancer which aids inner beauty and faithfulness.
Opal strengthens the will to live. It is believed to help cure depression and bring confidence to the wearer.
Wearing Opal is prescribed to assist in healing persons with ailments associated with memory, eye-sight, pineal and pituitary gland dysfunction.The Balancing Power of Colour

Red stones have generally been thought to be remedies for bleeding and inflammatory diseases,to provide a calming influence, and remove anger.
Yellow stones were believed to cure bilious disorders and diseases of the liver.
Blue stones are prescribed to both calm spirits of darkness and bring the aid of light and ensure sure-footedness.
Opals can match the best gemstones, tint for tint, and still find strength for laughter and dancing!
Protective Powers
The symbol of hope, an Opal is considered to hold all the talismanic virtues of the other stones.
The full spectrum of colours found in multicoloured Opals resonates with all Chakras and by maintaining balance and harmony can help protect the wearer’s physical and spiritual well being.

Pattern is undoubtedly what makes Opal such an interesting and most dazzling gemstone.
Stones within which images can be seen are very rare, they are well sought after by collectors worldwide. |

Sometimes the scene or picture is somewhat subjective perhaps resembling modern art, but other times its clearly a cat!
While every Opal has a unique pattern, there are seven categories of patterns that all Opals fit within: Pinfire, Flash, Broad Flash, Rolling Flash, Harlequin, Rare Patterns and Picture Stones. Over 90% of stones have Flash and Broad Flash patterns.
Rare Patterns: Highly collectible in Opal, they only seldom appear and even experts will see very few examples throughout a career in the industry. These include the phenomena of Chatoyancy and Asterism, that is Catseyes and Star Opal, an organically derived 'Fern' pattern (8) is another. Often given interesting names which may also vary widely, like 'Chinese Writing' or the famed 'Harlequin' - a rare pattern indeed! Carefully defined, Harlequin Opal has square or angular patches that can be seen at arms length. Floral and Flagstone patterns are often mistaken for Harlequin yet they are not nearly as rare. An expert can expect to see one or two in their lifetime at best.
Picture Stones: Opals which create a picture with their pattern, sometimes in conjunction with inclusions, that reminds us of a specific object. Whereas rare patterns may be repeated periodically, picture stones are more varied and they are given names which reflect this.

‘Hercules’ a matrix picture stone found at Opalton in discarded mullock heaps on the fossicking reserve by Colin Duff c.1991. Pictured next to several possible likenesses, Hercules wearing the lions head, Freud’s thinking man, and a Spanish Conquistador.
Fun Stones: Low to medium grade Opals of considerable size, usually varieties of Boulder Opal; Yowah nuts, matrix, splits, slabbed or sectioned sets and specimens. Potch, ironstone and scene-like inclusions, which the lapidary would otherwise remove when cutting a gemstone, are retained in the face of the polished article. From such stones often more subjective or imaginative pictures can be interpreted and each person may see different things within them.

Structure Lines: Lines in an Opal where the internal structure of the Opal, the size and/or alignment of the silica spheres, has changed. Not cracks. These often provide the basis for unique designs or patterns as seen in picture stones. They also provide the outlines for carvers to follow on from with their craft.
Cameos: Carved out of gem materials with integral layers or banding, such as banded agate, shell or Opal of every variety, preferably where different layers have contrasting colours.
Stone cameos of great artistry were made in ancient Greece as far back as the 6th century BC. This carving technique features a raised (positive) relief image and as opposed to the 'intaglio' method which has a negative relief image. Both technologies were also used to adorn the world’s first coinage issued around that time. Cameos were populary worn as jewelry by the Romans and a few rare Opal cameos are attributable to the period. Cameos have since enjoyed periodic revivals, notably in the early Renaissance and during Napoleon’s reign. Queen Victoria was a major proponent of the cameo trend to the extent that they would become mass produced by the second half of the 19th century.

Hand-worked portrait cameos are extremely challenging for a gemstone carver to execute. Very few crasftspeople possess the combination of skill, highly developed artistic ability, and years of experience needed to create life-like portraits.
Opal is a relative newcomer to the carver’s stock of materials. William Schmidt, an English carver, documented that he was the first to carve Opal into cameos in 1874. In a letter to A. Booth he wrote that he invented a process of cutting Opal cameos in such a way as to utilize the matrix of the rough Opal for the ground colour and emphatically insisted that no antique or fifteenth century Opal cameos existed. Schmidt carved his cameos from the newly discovered Boulder Opal variety found in Queensland Australia in the early 1870’s. Schmidt’s Opal cameos were exhibited in the 1878 Paris Exhibition by John Brogden and received a gold medal. They were acclaimed by the
Mr Brogden shows a neck ornament which in its nature is unique. The gems in this beautifully designed piece of decoration are camei, each being cut from an opal or the matrix of an Opal. Now, to appreciate the delicacy of such a carving, it must be remembered that the iridescence of this curious stone is due to the minute fractures by which its entire substance is traversed, just as though it had been shivered by some natural shock. As may well be imagined, the splintered formation of the Opal renders it an exceedingly impracticable stone to cut; and though here and there a carved or engraved Opal may be met with, this kind of workmanship is so rare that a cameo necklace must be accounted a wonder of wonders in the jeweller’s art.
Nowadays, the vast majority of subjects (other than commissioned portraits) are not carved by hand, the traditional themes of classical scenes from mythology or a standard image of a young lady, are more likely to be made with the aid of an ultrasonic mill or carving machine. Multiple copies of a master design can be produced relatively quickly, by pressing a master die onto the stone blank. The result is a cameo that has a satin surface texture described as "freshly fallen snow", by gemmologist and author Anna Miller. This texture and the lack of any undercutting are used by appraisers as evidence to prove that a cameo is machine-made.
Assembled cameos, made by setting a carved Opal relief onto a backing of ironstone are mass produced in Hong Kong, just like doublets they can be readily identified.

ORIGIN AND HISTORY
A myth from the Aborigines of Australia tells of the birth of Opal: “...the creator came down to Earth on a rainbow, with a message of peace to all the people. And at the very spot, where his foot touched the ground, the stones became alive and started sparkling in all the colours of the rainbow.”
Opal is the embodiment of ' THE SPIRIT OF THE CHILD' - To the ancient Greeks it was known as paederos, the derivation of this meant both 'child' and 'favourite' - inferring that it had the kind of peerless beauty of a child.
Opal n. an amorphous form of hydrated silicon dioxide that can be of almost any colour and may contain all the primary colours and many more tints or hues besides. It is used as a gemstone. [from Greek Opthalmios, ‘the eye stone’ or ‘eye lotion’; from Latin Opalus, Gk. Opallios ‘to see a change’, from Sanskrit Upala ‘precious stone’] – Opaline adj. [Opal entered the English language as Opal around 1586]POPULARITY
Gemstone names, such as Pearl or Ruby, became popular in the 19th century, but Opal was not one of the more fashionable of these names.
Opal has not appeared in the top 1000 baby names since 1960, when it ranked at number 920. Popularity dropped substantially in the 1950s, though popularity had been in decline for several decades.
The name Opal saw the height of its popularity in 1911, when it ranked at number 81.
Other Gemstone names, such as Amber and Jet have increased in popularity in the late 20th century, Opal may yet experience a revival.

Love, Luck & Power
Opal Magic
THE ART OF LOVE
Opal - 'The stone of Lovers and Artists' - has always been associated with love, hope and desire.
The ancient Greeks and Romans referred to Opal as the 'Cupid Stone', because it suggested the clear complexion of the god of love.
The seductive nature of Opal intensifies emotional states and releases inhibitions inspiring passion and romance.
Opal stimulates originality and creativity whilst encouraging an interest in the arts.
LUCK & THE POWER OF LOVE
Opal enhances cosmic consciousness and induces psychic and mystical visions.
The psychological ability to love oneself is amplifed by wearing opal, helping you realise your full potential.
Wearing an opal brings loyalty, faithfulness and spontaneity as it encourages the wearer to put out positive emotions.
Thus, Opal is a karmic stone teaching that what you put out comes back. You make your own Luck!
LOVING WORDS
In 18th century France and England, jewellery was often set with gems the first letters of which, combined, formed a motto or expressed a sentiment. Some of the more common ones relating to Opal appear below.
|
SOUVENIR
POWER
GOOD LUCK |
![]() |
FOREVER
LOVE ME
HOPE
BONHEUR |
In the sentimental late nineteenth century, this practice was repeated, and it is still used by romantics today. Word association or the use of one's own initials can add another dimension to a piece of jewellery, it helps to tell a story which makes for an excellent heirloom.
|
DEVOTIONAL JEWELLERY Various articles of jewellery have long been associated by use and decoration with religion, although some also have decoration of a secular nature or were used for superstitious reasons or supposed magical powers. Devotion to one's beliefs, dedication to one's family, queen or country and the earnest attachment of a mother to her children are themes which are continually revisited in jewellery design: These bracelets belonged to Empress Josephine (1763-1814) and have ultimately been inherited by Queen Margrethe II of Denmark. |

| One bracelet with eight stones and 157 diamonds reads EUGENE (Emeraude, Unaktie, Grenat, Emeraude, Nicolo, Emeraude). The other with six stones and 147 diamonds reads HORTENSE (Hessonite, Opale, Rubis, Turquoise, Emeraude, Nicolo, Saphire, Emeraude). By her first marriage to Alexander Beauharnais, Josephine had 2 children who were adopted by Napoleon, her son Eugene and daughter Hortense. |
THE POWER OF COLOUR
The symbolism of colour has always played an important role in recommending particular gemstones for special purposes in jewellery:
Red stones have generally been thought to be remedies for bleeding and inflammatory diseases,to provide a calming influence, and remove anger.
Yellow stones were believed to cure bilious disorders and diseases of the liver.
Green stones traditionally have been suggested to correct diseases of the eyes.
Blue stones are prescribed to both calm spirits of darkness and bring the aid of light and ensure sure-footedness.
Because Opals may display all the spectral colours they relate harmoniously with all of the body's energy centers or Chakras.
Opals can match the best gemstones, tint for tint, and still find strength for laughter and dancing!
PROTECTIVE POWERS
Opal is a protective stone which can help make the wearer unnoticeable or 'invisible', particularly helpful in negotiating ventures into dangerous places.
Opal strenghthens the will to live!

Cutting: Pleasure, Value Adding or Profession ?
Cutting Display, London Exhibition 1886 |
Opal cutting is a specialised job but many miners do cut their own. Others prefer to leave it up to the cutter,wholesaler or manfacturer to decide the shape and cut appropriate for making jewellery.
|
Cutting, Opalton QLD 1902 |
The first lapidaries on the Australian Opal fields at the turn of the century rigged up sewing machines, bicycles etc. creating hand or foot operated contraptions with which to cut and polish Opals.
Some miners prefer to sell completely rough material just as they find it, others choose to block and face, or 'rub' it to reduce the element of hidden surprise. |
|
Opal Cutters Camp,3 Mile Lightning Ridge 1910 |
There has always been a strong demand for cutters services on the opal fields, particularly in Lightning Ridge where most of the Opals found are sold as cut and polished gems by their finders. There a single stone may provide enough money on which to retire.

Caring for Opal
Treat Opal with care as you would any precious gem or investment; avoid heavy blows, abrasives, harsh chemicals and extreme heat.
Although you probably would not wear any gemstone jewellery while gardening or washing the dishes, solid Opal jewellery is actually best cleaned using a soft cloth and mild kitchen detergent in cool water.
Because water is part of its composition, Opal is a ‘living gem’ which should not be subjected to extreme heat and may be susceptible to dehydration.
Therefore:
1. If Opal is to be stored for protracted periods it should not be subjected to overly dry conditions such as those found in a bank safety deposit box.
2. Opals should be worn regularly as they are nourished by contact with their wearer.
3. The use of an ultrasonic cleaner for Opal jewellery is not recommended.
4. Opals should not be treated with mineral oils or glycerine despite its common but misguided use to store opal specimens. Clean or demineralised water is a better alternative for storage.
If you wish to have loose Opal set, be sure to find a reputable jeweller who is familiar and comfortable working with Opal. Have a go and design your jewel.
After a long life of steady use Opal jewellery may need re polishing, it is best to take it to an expert, preferably who sold it to you.
|
Note* Opal is a 'living gem' as are pearls, both are somewhat delicate gemstones, as are emeralds. Once mounted in a setting all gemstones are equally as vulnerable, including diamonds, which may chip (cleave) and fallout of their settings. Therefore all gemstones and jewellery should be handled respectfully. Sources & Image Credits: EXTRA LAPIS, No. 10.
