When it comes to colored gemstones, we have a lot of customers who want something different than the status quo and our response is almost always one of the Phenomenal Gemstones. What are those? They are a group of gems that display a visual phenomenon not seen in normal gems. These gemstones can be grouped into 8 categories, which are typically named by the phenomenon they show. The gem species with the most phenomenal traits in it is Feldspar. However, there are a few other species that also have phenomenal gems in their family. In this post, we will discuss the 5 categories of phenomenal gems and give some examples of each.
Asterism
Asterism is a fascinating optical phenomenon seen in gemstones where a star-shaped pattern appears when light is reflected on the surface. This effect is caused by the presence of needle-like inclusions within the stone. Some well-known examples of gemstones that exhibit asterism include star sapphires, which display a six-rayed star when cut in cabochon, and star rubies, known for their crimson hue and intersecting star pattern. Other notable stones showcasing asterism are star diopside, star garnet, and star rose quartz.
Gem enthusiasts often appreciate the unique beauty of asterism in stones, as it adds a captivating allure to jewelry pieces. Star sapphires, in particular, are highly sought after for their mesmerizing star patterns that seem to shimmer and dance when exposed to light. Star rubies, with their deep red color and distinct star shape, are also prized for their rarity and visual appeal. Whether in the form of pendants, rings, or earrings, gemstones displaying asterism are sure to capture attention and spark admiration.
In addition to their aesthetic value, gemstones with asterism are believed to possess metaphysical properties by some cultures. Star sapphires, for instance, are thought to bring good luck and protection to the wearer, while star rubies are associated with vitality and passion. Whether you are drawn to these stones for their visual allure or symbolic meanings, exploring the world of asterism in gemstones can lead to a deeper appreciation for the wonders of nature and the artistry of lapidary craftsmanship.
Adularescence
Adularescence is the optical phenomenon where a gemstone exhibits a milky, bluish light that seems to move across the surface when the stone is rotated. This effect is caused by light scattering from microscopic inclusions or structural anomalies within the gemstone. Moonstone is the only example of a gemstone that displays adularescence.
Moonstone is a captivating gemstone known for its unique appearance and mystical properties. It is a type of feldspar mineral that exhibits a shimmering adularescence, giving it a milky appearance with a soft blue sheen. Moonstone is often associated with intuition, balance, and new beginnings, making it a popular choice for jewelry with spiritual significance.
Chatoyancy
Chatoyancy is a fascinating optical phenomenon seen in certain gemstones. This effect, also known as the “cat’s eye effect,” is characterized by a band of light that moves across the surface of the stone when it is turned. This shimmering effect is caused by the reflection of light on parallel inclusions or fibers within the gemstone.
One classic example of a stone that exhibits chatoyancy is tiger’s eye. This beautiful gemstone, with its golden to red-brown color and silky luster, displays a captivating chatoyant band that resembles the eye of a cat. Another well-known stone that showcases chatoyancy is chrysoberyl, specifically the variety known as cymophane or cat’s eye chrysoberyl. This gemstone displays a striking milky or opalescent band of light that glides across its surface.
Other notable examples of stones that display chatoyancy include hawk’s eye, apatite, and scapolite. Each of these gemstones exhibits a unique play of light that adds depth and intrigue to their appearance. Whether in jewelry or as part of a gemstone collection, these chatoyant stones never fail to captivate with their mesmerizing optical effects.
Aventurescence
Aventurescence is a phenomenon where a mineral or stone exhibits a sparkling effect. This effect is caused by the presence of reflective inclusions within the stone, such as mica or hematite. When light hits these inclusions, it creates a shimmering or glittering appearance, adding a unique and eye-catching quality to the stone.
Several stones are known for displaying aventurescence. One popular example is aventurine, a form of quartz characterized by its green color and metallic sheen caused by inclusions of fuchsite or hematite. Another well-known stone exhibiting aventurescence is sunstone, which features a bright, reflective effect due to the presence of hematite or goethite inclusions. These stones are often used in jewelry making to add a touch of sparkle and elegance to various pieces.
In addition to aventurine and sunstone, other stones that can exhibit aventurescence include moonstone, labradorite, and tiger’s eye. Each of these stones showcases a unique play of light and color, making them popular choices for jewelry enthusiasts and collectors alike. Whether in the form of beads, cabochons, or faceted gemstones, aventurescent stones continue to captivate with their mesmerizing beauty and charm.
Iridescence
Iridescence is a phenomenon where surfaces display a colorful sheen that changes with the angle of view. This optical effect is caused by the interaction of light with a material’s surface structure. Examples of stones that exhibit iridescence include ammolite and fire agate.
Ammolite and fire agate are two stunning gemstones that captivate with their unique beauty. Ammolite, formed from the fossilized shells of ammonites, displays a mesmerizing array of iridescent colors, making each piece truly one-of-a-kind.

Labradorite, a feldspar mineral, is known for its striking appearance with hues of blue, green, gold, and sometimes even purple. The iridescence in labradorite is a result of light interference within the stone’s structure, creating a mesmerizing display of colors.
Labradorite is a popular gemstone used in jewelry making and is highly sought after for its labradorescent properties.

Play Of Color
Play of color in opals, also known as opalescence, is a unique optical phenomenon that causes the gemstone to display a spectrum of colors when viewed from different angles. This captivating effect is a result of the diffraction of light as it passes through the tiny silica spheres that make up the structure of opals. The colors seen in opals can range from vibrant reds, oranges, and yellows to soothing blues, greens, and purples, making each opal a truly one-of-a-kind gemstone.
Opals are classified into two main categories based on their play of color: precious opals and common opals. Precious opals exhibit a distinct play of color, with patterns that can include pinfire, harlequin, and broad flash. These opals are highly valued for their unique beauty and are often used in fine jewelry pieces. On the other hand, common opals do not display a play of color and are typically opaque or translucent in appearance. This renders them more affordable and accessible to a wider range of consumers.
When choosing an opal, it is important to consider the play of color as a key factor in determining the gemstone’s quality and value. The intensity, variety, and distribution of colors within the opal can greatly impact its overall beauty and desirability. Whether you are drawn to the fiery reds of a black opal or the tranquil blues of a crystal opal, the play of color in opals adds a magical element that makes each gemstone a true work of art.
Color Change
Color Change gemstones are a unique category of gems that exhibit a fascinating phenomenon of changing color under different lighting conditions. This optical effect is caused by the presence of trace elements within the gemstone’s structure. Some popular examples of Color Change gemstones include Alexandrite. It shifts from green in daylight to red under incandescent light. Fluorite, known for changing from blue under natural light to purple under artificial light. Color change gemstones are highly sought after for their mesmerizing beauty and rarity in the world of gemology.

Cons Of Some Phenomenal Gemstones
Phenomenal Gemstones, while often admired for their beauty and rarity, can come with their own set of drawbacks. Some phenomenal gemstones, such as opals and pearls, are known for their delicate nature. These stones can be easily scratched or damaged, requiring extra care and attention when handling or wearing them. Additionally, certain gemstones may require special cleaning methods to maintain their luster. This makes them more high-maintenance than other types of jewelry.
Another downside of some phenomenal gems is their susceptibility to discoloration or fading over time.

Regular maintenance and proper storage are essential to preserve the beauty of these gemstones.
Furthermore, some phenomenal gemstones can be quite expensive to acquire and maintain. The rarity and unique qualities of these stones often result in higher price tags compared to more common gemstones. Additionally, specialized care, such as professional cleaning or repairs, may also come at a premium cost. As such, individuals considering purchasing phenomenal gemstones should be prepared for the investment required not only in buying the stone but also in its long-term care and upkeep.
