One of the most exquisite and expensive stones in the world is the opal. Perhaps you’ve heard of opals as birthstones or are considering purchasing one for a friend or loved one? We’ll define an opal, describe its origins, and provide some suggestions for selecting opal jewelry.

What is opal?

Sedimentary rocks often include the gemstone opal. The usage of opal as an ornament dates back to antiquity, with the oldest mentions of opals occurring between 3600 and 3000 B.C. in Central America and Mexico. Additionally, it is used as a material for religious ornaments, amulets, and body jewelry.

A well-known gemstone with a long history of usage is the opal. Opal is a kind of microcrystalline quartz that serves as the base material for opal jewelry. Due to the high iron concentration, it has a white to light blue color. It has been fashioned into decorations and jewelry because it is lovely to gaze at day or night or in the sun.


The usage of opals dates back more than 25,000 years. The Australian aborigines were the first to find this unique stone, and they did so in the Omafiets River in the center of the Northern Territory. They were given the name “opal” about 2000 B.C. because the word “opal” means “fire” in an Aboriginal language, which also explains why they are sometimes dubbed “fire opals.”

For thousands of years, people have valued opals, a stunning gemstone. Originally employed as gemstones in antiquity, they have had historical acclaim. Despite the fact that opals are now widely available in jewelry shops throughout the globe, many people still think stones have supernatural properties.


Australia, Central America, and ancient Egypt all have opal deposits. Opal is now found all over the globe (Brazil, Mexico, Honduras, and the western US), but Australia, where it is the official national gemstone, produces 95% of the valuable kind.

Opal Properties

Opal is a silica stone that is translucent and prized for its display of color and sometimes tricolor look. Opal stones are sometimes referred to as the “gem of truth” and are believed to provide their users with mental clarity and a sense of purpose in life. The composition of the opal stone itself will affect its unique qualities.

Opal is a type of mineraloid. Because it is a hydrous type of silica, water is trapped inside its structure. Depending on how much water is contained in the opal, the color may range from transparent to opaque.

Types Of Opal

Opals come in two colors: black and white. Opals are most often found in black rock formations that were formerly mudstone or other dark-colored bodies of water. White opal is the most common variety of opal. These rocks are assumed to have developed thousands of years ago, when these regions were still submerged in water, as a result of magma cooling below and being exposed to air during volcanic eruptions.

Opaque opals with a black body color are known as black opals. It comes in many hues, but red and orange-red are the most prevalent.

White opal has a white hue and is translucent or transparent to light. Greyish whites, light blue-greens, yellowish whites, and even pinkish whites are the most prevalent colors for white opals.

When seen under a microscope or with UV light, fire opal is an opaque variety of brown porcelainized quartz (silicified feldspar) that contains iron impurities that give the outer surface of the material a reddish tint. The name “opal” encompasses not only this specific kind but also any other valuable stone whose source material includes hematite (FeO).

Uses Of Opal Jewelry

Opal jewelry represents luck, hope, and purity. It also serves as a metaphor for passion and love.

The beauty and rarity of opals have led to their usage as opal jewelry for thousands of years. The Red Centre of Australia is home to the most prevalent kind of opal, which naturally occurs in sandstone formations known as opaline silica (silica-rich sandstone).

How to Tell If an Opal Is Real?

  • Examine the stone in the daylight. If it has no holes or fissures and resembles any other rock, it most likely isn’t an opal.
  • Examine the stone in direct sunlight or under UV lights (UV exposure may cause harm to certain specimens). This makes it simpler to notice whether your item has any surface flaws; if there are any cracks or scratches, this may be a sign that it isn’t at all natural.

How to Assess an Opal’s Value?

  • The most crucial feature to consider while examining an opal is its color. You must not skip this one! It will provide you with all the information you want about an item.
  • Another factor that requires your attention is the way the colors interact in opals. If every color is the same, it could not have any commercial value. On the other hand, if there are several hues, it can be worth more than you think!
  • Patches or patterns on an opal may also be a sign of its value; if they are fine and smooth, like those on quartz crystals, they won’t be very valuable; however, if they are rough-looking with sharp edges, like those on jasper stones, there is a good chance that these patches were brought on by repeatedly striking against hard surfaces, and they will likely be very expensive.
