Check the country of origin. Most real opals are mined in Australia, which is the opal capital of the world. Russia and Hong Kong make high quality fake opals that some shady jewelers try to pass off as the real thing. If your opal does not come from Australia then you should seriously suspect its validity. Inspect the symmetry. If the opal is a natural stone, then even with cutting and polishing it may not be entirely symmetrical.

If the opal is a perfect circle or oval, then you should have a licensed jeweler inspect it before you make the purchase.

Look at the opal in strong, white light. Do not use a fluorescent light, because it can make the opal appear to have more facets than it actually does and can give the impression of additional colors. If the opal seems to have multiple layers of color, then this is a good indication that it is the real thing. However, if an opal only appears to have colors immediately below the surface, it may be a fake. Check the price. Look closely at the pattern.

An opal created in a laboratory Gilson opal displays bright colours in large patches of colour.The word opals typically conjure images of black or white stones, sparkling with a captivating play of color as fire dances across its surface. Many are stunned to learn, however, that opals are found in an amazing variety of colors! Oregon peach opal represents one of these rare and unusual color varieties. The pink material is swirled with peachy tones evocative of freshly scooped sherbet.

This peach opal is what's known as a 'common opal. It's simply a term to differentiate opals that possess the characteristic play of color from those that don't. Instead, these stones possess a captivating and intense body color, making them beautiful in their own right. Stones are not treated in any known way. These opals are opaque and are shaped into cabochons. Occasionally, the rare specimen will be faceted.

Peach opal ranks 5. As with all similar stones, Oregon peach opals are vulnerable to high heat and chemicals, and jewelry should not be exposed to either.

They can be cleaned with warm, soapy water. Opal gemstones require the moisture found in air to stay in good shape. Avoid storing them in airtight containers. In fact, opals have a history of being connected to this month as a birthstone since at least the early s. American mineralogist G. Kunz once remarked how opal exemplifies October and displays the contrasting colors of autumn in its possible color combinations. Peach opal contributes to this tradition, the gem showing color like a changing leaf in fall.

Opal, however, is not associated with any star sign. You may have even heard the adage suggesting only to wear an opal if it's your birthstone. In antiquity, however, opals were one of the most coveted stones around. In ancient beliefs, gemstones were identified by their color, and opals, with their play of color, were frequently considered to possess the power of all other gems.

So, what changed? Firstly, by the nineteenth century, consumers held jewelers to greater responsibility for damaged goods, and the often-fragile opal could be difficult to work with, lending it an air of misfortune. In this story, "Anne of Gerstein," the character Hermoine met an unfortunate end, and the opals associated with her acquired this same unlucky reputation.

Queen Victoria suffered an embarrassing wardrobe malfunction during her coronation, later blamed on an opal fastening pin which became undone. And King Alphonso XII of Spain, along with his wife and other family members, all died after wearing an opal ring the kind had commissioned for his queen.

In medieval lapidary texts, opals might sometimes be described as ophthalmius literally "eye stone"in recognition of this quality. Coupled with its presumed vision-enhancing attributes opals were also considered to be the patron stone of thieves. Opals come in a surprising variety of colors and types, from locations the world over. Oregon peach opal is a new find and has not been offered nationally before.

Shop LC is excited to be the first to bring this impressive stone to market.To be sure, there have been price increases, but when compared with aqua opal, red, and the pastels, it has been a laggard. This is a 70 percent increase. Not too shabby. It is only when compared with the aqua opals, pastels, and reds that it appears so small. There have been some dramatic exceptions where one-of-a-kind peach opal rarities are concerned. While none of the few known Fruit Salad peach opal punch sets have sold.

The prices on these pieces have not kept pace with the pastels or any of the other opalescent edge colors. Why is this so? I feel it is basically a matter of supply and demand. Peach opal was made in volume and is certainly much more available than aqua opal or the very limited blue opal, amethyst opal, red opal, or lime green opal. Coupled with this is the fact that many collectors find peach opal less appealing from an aesthetic point of view.

Some will also argue that it comes down to the fact Northwood made most of the aqua opal pieces, while Dugan-Diamond made the great bulk of the peach opal. They feel the Northwood patterns are simply more beautiful and desirable. For sheer beauty a peach opal display on a dark background is hard to beat. There are very few patterns that were made in both peach opal and aqua opal. Both colors are very rare in this piece. Due to the superb research efforts of Bill Heacock, we now know that Dugan-Diamond made some 90 percent of all the peach opal.

To my knowledge, Imperial and Millersburg made none.

Donā€™t Write Off Peach Opal

It is also doubtful if any was made by Northwood. The signed peach opal Nautilus is believed to have been made by Dugan-Diamond from an old Northwood mold left behind when the plant was sold in Dugan-Diamond did not bother to remove the signature. One signed peach opal Beaded Cable rose bowl has also turned up. This piece could also have been made from a carryover mold as we know that this piece, like Nautilus, was made earlier by Northwood in custard.

The peach opal Grape and Cable bonbon is also a one-of-a-kind. It is unsigned, but so are a number of these pieces in other carnival colors. It is quite likely that it, too, was made by Dugan or Diamond.

This piece was made by Northwood in milk glass with marigold iridescence, but this is not to be confused with true peach opal. At this point it would appear that Fenton and Westmoreland were the only companies other than Dugan-Diamond to produce any peach opal, and their production was minimal. Fenton, as previously mentioned, used this color for Dragon and Lotus, Blackberry Banded hat shapes, and a single Orange Tree plate is known.

A one-of-a-kind rare Orange Tree hatpin holder is also known. It is in the Loescher collection in Beloit, Wisconsin, unless George has needed some money very badly.

A rare Stag and Holly bowl has also been confirmed recently. It is often difficult to know which production to attribute to Dugan and which to Diamond since, like Northwood before them, they each operated from the same factory site at Indiana, Pennsylvania. The ad shown here is from a Butler Bros.

It is deposited at a relatively low temperature and may occur in the fissures of almost any kind of rockbeing most commonly found with limonitesandstonerhyolitemarland basalt.

There are two broad classes of opal: precious and common. Precious opal displays play-of-color iridescencecommon opal does not. Depending on the conditions in which it formed, opal may be transparent, translucent or opaque and the background color may be white, black or nearly any color of the visual spectrum. Black opal is considered to be the rarest, whereas white, gray and green are the most common. Precious opal shows a variable interplay of internal colors, and though it is a mineraloid, it has an internal structure.

It was shown by J. Sanders in the mids [6] [7] that these ordered silica spheres produce the internal colors by causing the interference and diffraction of light passing through the microstructure of the opal. Where the distance between the regularly packed planes of spheres is around half the wavelength of a component of visible lightthe light of that wavelength may be subject to diffraction from the grating created by the stacked planes. The colors that are observed are determined by the spacing between the planes and the orientation of planes with respect to the incident light.

The process can be described by Bragg's law of diffraction. Visible light cannot pass through large thicknesses of the opal. This is the basis of the optical band gap in a photonic crystal.

The notion that opals are photonic crystals for visible light was expressed in by Vasily Astratov 's group. The term opalescence is commonly used to describe this unique and beautiful phenomenon, which in gemology is termed play of color. In gemology, opalescence is applied to the hazy-milky- turbid sheen of common or potch opal which does not show a play of color.

Opalescence is a form of adularescence. For gemstone use, most opal is cut and polished to form a cabochon. Opals too thin to produce a "solid" may be combined with other materials to form attractive gems.

An opal doublet consists of a relatively thin layer of precious opal, backed by a layer of dark-colored material, most commonly ironstone, dark or black common opal potchonyx, or obsidian. The darker backing emphasizes the play of color, and results in a more attractive display than a lighter potch.

An opal triplet is similar to a doublet, but has a third layer, a domed cap of clear quartz or plastic on the top. The cap takes a high polish and acts as a protective layer for the opal. The top layer also acts as a magnifier, to emphasize the play of color of the opal beneath, which is often an inferior specimen or an extremely thin section of precious opal.

Triplet opals tend to have a more artificial appearance, and are not classed as precious gemstones. Jewelry applications of precious opal can be somewhat limited by opal's sensitivity to heat due primarily to its relatively high water content and predisposition to scratching.

Doublet opal also has the added benefit of having genuine opal as the top visible and touchable layer, unlike triplet opals. Besides the gemstone varieties that show a play of color, the other kinds of common opal include the milk opal, milky bluish to greenish which can sometimes be of gemstone quality ; resin opal, which is honey-yellow with a resinous luster; wood opalwhich is caused by the replacement of the organic material in wood with opal; [11] menilitewhich is brown or grey; hyalitea colorless glass-clear opal sometimes called Muller's glass; geyseritealso called siliceous sinterdeposited around hot springs or geysers ; and diatomaceous earththe accumulations of diatom shells or tests.

Common opal often displays a hazy-milky- turbid sheen from within the stone. In gemologythis optical effect is strictly defined as opalescence which is a form of adularescence.

Fire opal is a transparent to translucent opal, with warm body colors of yellow to orange to red. Although it does not usually show any play of color, occasionally a stone will exhibit bright green flashes. Fire opals that do not show play of color are sometimes referred to as jelly opals.Two specimens of Oregon Sunstone: The specimen on the left is a round cabochon weighing 2.

It is a stone that is heavily included with visible platelets of copper. Those platelets are what reflect light to produce sunstone's aventurescent effect. The specimen on the right is a clean faceted stone weighing 1. It is an oval-shaped stone with a strong orange color. Oregon is one of the nation's leading states for the production of gemstones. These gemstones are mostly a result of the state's long volcanic history.

Oregon's famous sunstone is produced from basalt flows, thundereggs are formed in rhyoliteand the silica that produced much of Oregon's opalagate, and jasper was dissolved from volcanic rocks by hot groundwater. In the sections below we feature Oregon sunstone, thundereggs, opal, and the chalcedony gems of agate and jasper. Oregon has many other gems, which include obsidiangarnetjadesteatite, wonderstone, and many varieties of petrified wood. Oregon produces some of the best gem-quality feldspar in the world.

The name " Oregon Sunstone " is used for gem-quality feldspars from Oregon, with and without aventurescence. They can be found in colors that range from clear through yellow, orange, pink, red, green, and blue. Multiple colors are often found in the same crystal, making bicolor and tricolor stones possible.

Some specimens of Oregon Sunstone contain microscopic copper platelets suspended throughout the material. These platelets are often in alignment within the stone, and light entering the stone at the proper angle will simultaneously reflect from them.

When these stones are played in the light, bright copper-colored flashes are produced as the stone passes through the angle of reflection.

Flashes can also be observed by moving the light source or changing the angle of observation. This interaction with light produces the phenomenon known as aventurescence. Sunstone is cut into faceted stones and cabochons.

Material with platelets is usually cut to produce flashes of light when the stone is viewed in the face-up orientation. To do this, the copper platelets should be parallel to the top and bottom of the stone. Quality material cut by a skilled artisan is so attractive that the State Legislature named Oregon Sunstone the state's official gemstone.

The sunstones are found as phenocrysts in a small number of basalt flows. This makes production a labor-intensive job. They can be screened by hand from soils which have developed above the basalts. Hard-rock mining of the basalt is sometimes done, but it is less successful because the feldspar cleaves easily and breaks during extraction. Oregon Thundereggs: Examples of thundereggs sawn to display their interior. The top two are halves of a single egg about three inches in diameter.

It is filled with gray chalcedony with gray agate and drusy quartz in the center. The bottom is a half egg about six inches in diameter with gray banded agate around the outside, white agate towards the center, and a drusy quartz cavity in the center. The most popular rock in Oregon is said to be the "thunderegg. Thundereggs can be ugly on the outside; however, when they are cut or broken open, a treasure of colorful gem material and crystals is often revealed. Thundereggs range in size from less than one inch to over three feet in diameter.
