What is a Jelly Opal?

What is a jelly opal? A gemstone with a pattern that looks like jelly, but is actually a solid color. A solid opal without color play is called an orange jelly. Some jewelers refer to such stones as fire opals and blue bottle potches. Here is a short list of common names for jelly opals. In case you’re curious, these gems are native to Australia and are worth thousands of dollars.


The opal gemstone was originally formed as a liquid, about 15-30 million years ago. The slurry settled into impervious clays at depths of 20 to 30 meters. Eventually, the slurry crystallized into the precious opal we see today. While the opal’s formation is relatively recent, its beauty is timeless. Its beauty has inspired artists and scientists to create various designs and patterns, including the opal pendants and rings that we’ve come to love.

While these opals are still classified as crystal opals, their value is lower than that of a white opal. However, a high-quality Ethiopian opal is the world’s most sought-after gemstone. Collectors and designers alike are highly attracted to these stones. Unfortunately, prices of these gemstones vary widely, so buyers should be very careful when buying a piece of jewelry.

Jelly opals are not as hard as opals, but they do have some unique characteristics. The transparent stone has different shades of color throughout. This makes them a favorite gemstone among lapidarists. Unfortunately, because their Mohs mineral hardness is very low, they are prone to chipping and breakage. However, the gemstones’ transparent properties make them an extremely popular choice for jewelry and collectibles.

The opal’s ‘play of color’ is created by a system of microscopic silica spheres interspersed throughout. The spheres act like a diffraction grating. Light passing through these spheres is refracted by their tiny holes, which in turn create the rainbow of colors we see in soap bubbles. The small spheres inside the silica gel are responsible for creating the ‘interference and refraction’ appearance. The silicon and oxygen chains are unevenly sized and the concentration is incoherent, resulting in an optical illusion similar to that of a soap bubble.


The gemstone opal, also known as the jelly opal, is a transparent precious stone that is found mostly in Australia and the Czech Republic. This gemstone exhibits a bluish sheen and a variety of colors, including greens, pinks, oranges, and even bright reds. While the vast majority of the opals found today are small, there are several varieties that are much larger and rarer.

Throughout history, people have attributed the opal with magical qualities. It was said to give the wearer a wider perspective and to clear buried emotions. It also helped to reduce inhibitions and foster spontaneity. Early Greeks believed the opal bestowed upon its wearer powers of foresight. In Arabia, the opal fell from heaven in the form of flashes of light. In Roman times, the opal was considered a symbol of hope.

The opals’ spiritual and magical significance has been incorporated into mythology and astrology. In particular, the opals’ connection with the triple burner meridian are believed to affect the immune system and govern our fight or flight response. Furthermore, the opals are said to enhance circulation. According to Leslie J. Franks, holding fire opals improves circulation and promotes good health.


A 6 carat Jelly opal, topped with a white diamond, is a beautiful specimen of this gemstone. It has many striking properties and is becoming increasingly valuable to collectors. The gemstone is remarkably clear, making any impurities easy to remove and polishing is an easier task than with most other stones. The large size of a Jelly opal also makes it an expensive gem, so the larger the piece, the higher the price.

A white jelly opal costs more than a similar colored one, but it is often slightly cheaper. The difference in price is usually due to the opal’s unique color zones. These colors are reflected off the surface of the gem, giving it a unique antique motif. If you are considering purchasing a Jelly Opal, you’ll want to consider several factors before making a final decision.

opal’s color is important. While all opals are valuable, green opals are among the most common. They can be very valuable when vivid and mixed with other colors, such as blue. The color is referred to as the ‘palette’. The most important aspect to look for in an opal is that it’s not scattered in color. Moreover, a good specimen should have continuous sheets of color.


There are many varieties of opal patterns. Some of the most popular patterns are harlequins, striped, and flagstone. Other opals feature a combination of patterns. Patterns may be more or less common, depending on the opal’s size and shape. Generally, the bigger and more distinct the pattern, the higher its value. Some opals display more than one pattern, and you can even find rare varieties with more than one.

The opals that are not clear can be split up and polished. Mexican fire opals are cut into rhyolitic host material and display a rainbow-like play of colors. Sometimes they have green flashes and are known as jelly opals. The pattern of jelly opal is best appreciated in larger pieces. Jelly opals are also quite expensive, and the price depends on the size and shape of the piece.

When a jelly opal exhibits a pattern of play-of-color, the colour of the digits is affected by the size of the silica spheres. The gaps in these opals vary in size. If there is an abundance of matrix, the digits are visible. On the other hand, if there is no matrix, the digits disappear. As a result, the digits in the pattern are often not continuous and may be a result of a slight misorientation in the silica sphere network.


The size of a jelly opal can vary widely. Generally speaking, the larger the piece, the more expensive it will be. The average jelly opal measures 13 x 10 mm, although they can be much larger. Gemstones that are cut into larger pieces are rare and more valuable. A jelly opal can be worth several thousand dollars. Here are some tips for choosing the right size for your needs.

Although jelly opals are considered crystal opals, they are less valuable than white opals. Opals that have more flash and color are more valuable. Ethiopian opals are said to be the world’s finest and are highly sought after by collectors. A sizeable jelly opal can sell for over AUD $25,000, but be careful when purchasing. The best way to find a high-quality opal is to look for one that is of a specific size.

If you’re looking for a larger opal, it is best to look for one that is a few carats larger than you think you’d like. Opals can range in size from one carat to 200 or 300 carats. They can range in price from inexpensive to expensive, but the bigger the stone, the more valuable it is. For this reason, buying a large-sized jelly opal can lead to better value in the long run.


If you’re curious to know how to value a jelly opal, you’ve come to the right place. These stones are often transparent and have a glassy luster, but they also display little to no play of color. A bright, cushion-cut hyalite, on the other hand, lacks any play of color and has a strong green reaction under SW UV light. However, it still exhibits a yellow-green reaction under sunlight. A moss opal, on the other hand, is white in color with dendritic inclusions.

The dominant color of the opal determines its value. Red, orange, yellow, green, indigo, and blue are the most valuable colors. An opal with blue or green flashes, on the other hand, is far less valuable. A well-crafted stone with a red or blue play of color will command more money. Check for the distribution of colors, as well as their contrast and abundance. The more even the distribution of the colors is, the more valuable it is.

Opals can be classified into two types – crystal and jelly. The former is a rare and beautiful gemstone and may be incredibly expensive. It can be regarded as a birthstone for people born in October, while the latter is a Mexican variety. While most opals come from Australia, some come from Ethiopia. Although these stones are less sensitive to heat, they should still be treated carefully and with care. Ethiopian opals are particularly sought after by collectors.
