Opals have mesmerized humanity for centuries with their kaleidoscope of colors and enchanting play of light. These unique gemstones have earned a special place in the world of jewelry and continue to captivate enthusiasts and collectors alike. However, not all opals are created equal, and the pursuit of the best quality opal is a journey filled with intrigue and beauty. In this article, we will delve into the mesmerizing world of opals, exploring what makes the best quality opal, how to identify it, and why these gems hold such a profound allure.
The Allure of Opals
Opals are unlike any other gemstone. Their ethereal beauty lies in their ability to refract and reflect light, creating a captivating display of colors. The term “opalescence” is often used to describe this unique phenomenon. Opals are known for their play-of-color, which can range from vibrant reds, blues, and greens to more subtle pastels and fiery oranges. This enchanting feature has made opals highly sought after for centuries, and they remain a favorite in the world of fine jewelry.
What is the Best Quality Opal?
To truly appreciate opals, one must understand the factors that contribute to their quality. The best quality opal possesses a combination of characteristics that set it apart from the rest. These key factors include play-of-color, body color, transparency, pattern, and size.
Play-of-Color
Play-of-color is undoubtedly the most crucial characteristic of opal quality. This term refers to the vibrant flashes of spectral colors that dance across the surface of the gemstone as it is viewed from different angles. The best quality opal displays a vivid and extensive play-of-color, with a broad range of colors and a captivating, dynamic movement. Colors should be well-defined and not too faint. Red and green are typically considered the most valuable colors in opals, followed by blue and purple.
Body Color
The body color of an opal serves as the backdrop against which the play-of-color occurs. The best quality opals often have a body color that is transparent or translucent, allowing the play-of-color to shine through. The body color can range from white to black, and the desirability of the body color depends on personal preferences and market trends. In some cases, black opals with a dark body color are highly prized for their striking contrast with the play-of-color.
Transparency
Transparency is another critical factor in opal quality. Opals can range from transparent to opaque. In general, transparent opals are considered more valuable because they allow the play-of-color to be more visible and vibrant. Opaque opals, on the other hand, may exhibit less play-of-color due to their reduced transparency.
Pattern
The pattern within an opal refers to the arrangement and distribution of the play-of-color. Some common patterns include harlequin (distinct squares or diamond shapes), pinfire (tiny, scattered specks of color), and floral (flower-like patterns). The best quality opals often feature well-defined, distinct patterns that enhance the gem’s overall beauty. The rarity and uniqueness of the pattern can significantly influence an opal’s value.
Size
Opal size can vary significantly, from small gemstones suitable for delicate jewelry to large, eye-catching pieces. The best quality opals come in various sizes, but size alone does not determine their value. A smaller opal with exceptional play-of-color and other quality characteristics can be more valuable than a larger opal with less impressive features.

Recognizing the best quality opal requires a trained eye and an understanding of the key factors that influence their value. Here are some tips to help you identify the finest opals:
Examine the Play-of-Color: The play-of-color should be vibrant and captivating. Look for a broad spectrum of colors, well-defined patterns, and dynamic movement as you tilt the opal.
Assess Transparency: Transparent or translucent opals are generally more valuable than opaque ones. Hold the opal up to light to check for its level of transparency.
Consider Body Color: The body color can impact the overall appearance of the opal. Some opals are valued for their dark body color, while others are preferred for their lighter hues. The choice depends on personal taste and fashion trends.
Evaluate Pattern: The pattern should be well-defined and enhance the opal’s beauty. Some patterns, such as harlequin and pinfire, are more sought after.
Check for Flaws: Examine the opal for any cracks, chips, or inclusions that may affect its durability and value. High-quality opals should be free from major flaws.
Seek Expert Opinion: When in doubt, it’s wise to consult with a certified gemologist or opal expert to help you assess the quality and value of an opal.
Caring for Opals
Opals are unique and require special care to maintain their beauty and durability. Here are some tips on how to care for your opal jewelry:
Avoid Harsh Chemicals: Opals are sensitive to chemicals, so it’s best to remove opal jewelry when using cleaning products or exposing them to chemicals. This includes household cleaners, perfumes, and cosmetics.
Protect from Abrasion: Opals are relatively soft gemstones, so they can be easily scratched. Store opal jewelry separately from other jewelry to prevent contact that could lead to abrasion.
Keep Away from Extreme Temperatures: Opals can be sensitive to temperature changes, so avoid exposing them to extreme heat or cold. This can help prevent the development of internal fractures.
Clean Gently: To clean opal jewelry, use a soft, damp cloth and avoid abrasive materials. It’s essential to be gentle during cleaning to prevent damage to the opal’s surface.
