All about Opal

Opal is a silicate mineral gemstone that can flash every color of the rainbow. There are several varieties of Opal, from Fire Opal, Precious Opal, and Black Opal. Several varieties of Opal are named for the shape of the play-of-color they display, such as Boulder, Crystal, and Matrix. 

Opal is primarily mined in Australia but is found around the world in various countries. Brazil, Mexico, and the Western US all produce Opal, but about ninety-five percent of the precious opal market is mined from Australia. 

Opal is the national gemstone of Australia. It is also the birthstone for the month of October. Opal is relatively soft and is between five and six on the MOH gemstone hardness scale. 

Opals should be carefully cleaned, only using soft cloths and soapy water. This gemstone has a high percentage of water content and can dry out, keep them out of prolonged direct sunlight and high heat. Otherwise, your Opal can develop cracking throughout the gemstone. 

Types of Opal

Water Opal

A water opal is a blue-gray stone with a light play of color. It has a look that is described as gelatinous. Another description could be that it looks like a plastic bag of water inside the stone. The play-of-color changes depending on the stone and is often not very bright. The colors that display in a water opal are amorphous and without distinct edges. 

Black Opal

Black Opal is found in only one country, Australia, and almost all of them have come from a single town, Lightning Ridge. Black Opals have a black backing to the clear layer of silica that reflects the prismatic colors of an opal. This backing, called potch, allows the colors in the Opal to reflect out of the gemstone more vibrantly. Black Opal is extremely rare and, because of this, is valued at a high price per carat for stones that display the best and brightest colorations. 

Fire Opal

Fire Opal is formed from the deep underground ancient volcanos in Mexico. They were revered by both the Aztecs and the Mayans and were found in ancient burials sites of both cultures. Fire-Opal differs from Precious or Common Opals in that the background ranges in color from deep yellows to bright red backgrounds. The play-of-color inside the stone is dulled because of the vibrant background coloration. Fire Opals are very valuable when the coloration and the play-of-color are exceptional and valued more than Precious Opals. Lower values occur when the color is yellow-toned, and the coloration inside is less brilliant. 

Common or Precious Opal

The term Precious Opal applies to any opal that shows a play-of-color. Generally, the white Opal is considered the standard of Precious Opal and is the Opal that is referred to the most when Opal is mentioned. Precious Opals display their colors when the light is moved over the Opal, when the Opal is moved under the light, and when the person viewing the Opal changes their perspective. 

Boulder and Matrix Opal

Both Boulder and Matrix Opalit refer to Opal that is so intertwined into a sandstone or ironstone rock that it is shaped as part of the gemstone. Boulder Opal generally is veins or pockets of Opal that form in the rock, and Matrix Opal refers to Opal that is distributed finely through the sediment grains. These Opals are typically referred to in measurements of size instead of carat weight. 

Opal History and Understanding the Lore of Bad Luck

At one time in history, back in Ancient Rome, Opal was prized as the most valuable stone, worth more than diamond. Opal was so valuable because of the rainbow play-of-color that the stone displayed; the Romans considered Opal the combination of all gemstones. Opal brought good luck to those who owned it. 

In the middle ages, Opal was thought to enhance eyesight and was known as the eye stone. That, in turn, became the lead-in on the stone being associated with the evil eye. It became closely associated with animals with evil eyes like cats and goats, and that was the association of bad luck with owning Opals. 

During plague times, Opal was thought to lose its color when the owner of the gem died. Opals are notoriously fragile to shape and cut into gemstones. Many lapidaries refuse to work with the stone as the stone is easily ruined because of its innate brittleness. 

Later on, in the 18th and 19th centuries, diamond sellers were worried that newly discovered Australian Opals would threaten their diamond sales, and they actively spread negative beliefs that Opals were bad luck.

Opals are fragile stones, and Double and Triple Opals- Opals that have been spliced together- are held together with glue and can be damaged by chemicals or even from soaking in water. Opals are about as hard as glass and do require special care. 

Alternatives to Opal

Moonstones

This milky gemstone displays adularescence or a shimmer from inside the gem. The gemstone is named for the display of moonlight on the water, and the soft blue-white glimmer from inside the stone is what makes it similar to Opal. If you are looking for a gem that moves with indirect eye lighting, this gem is a definite find for you. 

Labradorite

This mineral is made of feldspar, the most abundant natural material on earth. Labradorite is colored with bright swaths of color, in colors as rich as the rainbow. However, Labradorite does not have a play-of-color in such that the colors do not change as the stone is moved. The most popular Laboradorite coloration is a blue-green coloration, but red, yellow, purple, and orange color show are not uncommon. 

Rainbow Lattice Sunstone

Rainbow Lattice Sunstone originates in Australia, in a region called the Mud Tank Zircon Field. This feldspar mineral displays a rainbow lattice iridescence. Strips of hematite reflect rainbow coloration through the host mineral. The effect is iridescent as you move the stone, making it a similar example to opal.

Mystic Topaz

This rainbow fire gemstone displays a rainbow of colors. While it is a transparent stone, the display of colors from the stone can display many colors, while green and purple are the dominant colors. This gemstone is chemically treated to achieve this color effect, and it is a surface coating. While considered permanent, it can be scratched and damaged by stone chemicals.

FAQS

Question: Why has my Opal gone cloudy?

Answer: Opals have high water content and should be kept from drying out in a high dry heat environment or prolonged exposure to sunlight. Immersion in water can also damage an Opal; in man-created opals, the water penetration can cause the glue that holds layers together to break down, and the Opal will cloud and turn foggy or grey. 

Question: Why are opals considered bad luck?

Answer: Opals are considered to be bad luck to wear in recent history. In the Middle Ages, Opal was believed to be the ultimate gemstone and that it held the powers of all gemstones. However, unscrupulous diamond sellers are much at fault for the negative press the stone has received in modern times. The Opal is also a soft stone and is usually glued into a bezel, which means that caution and care must be taken when wearing and cleaning the stone not to damage it. 

Question: Is Mystic topaz a real stone?

Answer: Mystic Topaz is a real stone; it is a chemically enhanced white Topaz. The stone is coated with Titanium on the bottom stone to enhance the coloration of the stone. It is not coated on the top to avoid easy damage to his coating.

Question: What is the least expensive Opal?

Answer: White opals are usually the least expensive unless you also compare faux Opal, which are lab-created stones. Doubles and Triplet Opals are thinly sliced segments of Opal that have been layered with solid backing and topped with either White Topaz or Epoxy to create an Opal stone. These stones are much more affordable than solid opals. 

Question: Why is Moonstone so expensive?

Answer: The most beautiful examples of Moonstone came from Myanmar, but unfortunately, this gemstone had a limited amount to be mined and has been basically mined out. The blue-toned gems of the best grade are now being repurchased on the market and are essentially going up in price as they are becoming rarer. 

Bottomline

Caution should apply when considering an opal engagement ring. Engagement rings are typically worn daily and are subject to sometimes rough treatment, occasionally accidental knocks, and chemicals. When ranked by hardness, an Opal is a five or six on the MOH scale, where a diamond is a ten. Wearing Opal as a solitaire or center stone for a daily wear stone is a potential for a damaged stone. I would highly recommend having Opals as side stones or forgoing the stone as an engagement stone, but perhaps it could be part of another special ring or jewelry purchase.
