what is the value of opals

What is the value of opals? Opal is a naturally occurring gemstone that is made from silica. It is non-crystalline, that is, it does not contain crystals. These gemstones have a beautiful display of colors that is very visible and shines when light reflects on them.

Many jewelry lovers often ask what is the value of opals? Most of them really want to know how much opals are worth in the current jewelry market.

The value of opals is not easily figured out because there are many attributes of the gemstone that need to be considered. And also, the location of the opals plays a vital role in understanding the value of an opal.

Its unique and rich display of colors, coupled with the fact that it is also a rare gem, makes opals have high value and become pricey. Opals are mined in different countries of the world, including Ethiopia, the USA, Mexico, Brazil, Madagascar, etc.

However, Australia still stands on top as the most popular country where opals are mined. And, of course, they are the most expensive. Each country has its opals that are unique in their features, and this factor usually helps to determine the price and value of these gemstones.

This article post is focused on allowing you to fully understand the value of opals and how these different types of opal values are determined. Let’s get started.

What is the Value of Opals Per Carat?

Once opals are mined, they are cut and categorized as either opal doublet stones, opalized fossils, or rough opals. When this is done, the miners prepare the cut gemstones to be made into a variety of jewelry for the market.

Opals are always sold at a price per carat, and this can cost about $10 per carat up to $6,000 per carat depending on the type and category of the mined opals. After an opal is taken to be valued, a price per carat is given to enable jewelry buyers to get the full price of the particular opal ready to be sold.

The overall carat size or weight of the gemstone is used to determine the price of the opal.

Not everyone can easily measure the value of an opal. However, some variables can be used to carefully determine the value of opals.

They are the opal class or type, body tone, brilliance, pattern, color bar thickness, a play of color, and faults or inclusions. The size, location, and cut of the opals also contribute to the measurement of the opal values.

Let’s discuss these value variables one after the other.

1. Type of Opal 

This is regarded as the first variable to understand when trying to check the value of an opal. Opals can either be solid or be assembled into doubles and triples, which have just a very small piece of the opal placed underneath the assembly.

A solid opal would generally be worth much more in value than a doublet or triplet opal.

2. Body Tone

This refers to the background color of the opal, which can either be dark or light in tone. Opals with dark body tones are much more valuable than those with light body tones.

This is attributed to the fact that the darker body-tone opals can showcase more colors brightly than the lighter ones. It is common knowledge, however, that black opals are the most valued and pricey opals in the world.

3. Color Contrast

The play of color is achieved when the opal is faced with light and it displays its array of colors to produce a brilliant spectrum.

For this play of colors, the fire opal is much more valuable than the green opal due to its silica spheres, which allow it to display more colors when diffraction occurs.

4. Opal Brightness

This variable of the opal value determination refers to the brilliance and brightness of the colors displayed by the opal. The brightness fluctuates, especially when it is faced with white light, while creating a brilliant to dull appearance interchangeably.

5. Pattern

The pattern of the colored parts of the opal that forms the play of color is distinct to each opal type, as no two gemstones are the same. The color pattern displayed is also used to determine the value and uniqueness of the opal.

6. Color Bar

The thickness of the opal color bar in opals is also used to determine the value of the gemstone. Those with thin color bars are rated more valuable, like the Boulder opal.

However, once the gemstone has been cut into jewelry, the color bar does not hold much importance in determining the value of the opals.

7. Faults

Just as it is with any other type of jewelry or gemstone, once there is a visible fault, the value of that particular piece decreases instantly. An opal with an open crack has its value reduced.

A drop in the value of the opal can also occur when there are inclusions such as sand and other minerals, and color inconsistency.

Types of Opals and their Value

Opals are beautiful gemstones that are naturally occurring in nature. They are rated as one of the most expensive gemstones in the world and they are also rare.

Many believe that opals are formed by rainwater, although this has not been proved as no one knows how they are formed. Opals are also considered by some people as lucky gemstones with supernatural gifts.

In this post, we have compiled some of the common types of opals and their respective values.

The boulder opal is rated as the second-most valuable opal in the world after the black opal. Boulder opals are easily confused with black opals because of their dark body tone.

These gemstones contain ironstones, which enables them to exhibit their characteristic dark shade. Boulder opals can only be found in Queensland, Australia.

3. Australia Fire-Opal
