When it comes to gemstones, opals hold a revered place due to their stunning play of color and uniqueness. However, a similar-looking stone called opalite often confuses buyers and collectors. Though they might look alike to the untrained eye, opal and opalite are distinct both in their origins and properties. This article delves into the differences between opal and opalite, including their physical properties, uses, and value.
Understanding Opal
1. Natural Formation Opal is a natural gemstone formed from a solution of silicon dioxide and water. It is typically found in sedimentary rocks and forms over millions of years. Opals are renowned for their unique play-of-color, which is caused by the diffraction of light within the microstructure of the stone.
2. Physical Properties Opals are hydrated amorphous forms of silica with a water content that can range from 3% to 21% by weight. The most prized opals exhibit a phenomenon known as “play-of-color,” where the stone displays a spectrum of colors under light. This is due to the internal structure of the opal, which diffracts light.
3. Uses Opals are primarily used in jewelry due to their aesthetic appeal. They are often set in rings, necklaces, and earrings. Beyond their beauty, opals are also believed to have metaphysical properties, including enhancing creativity and self-expression.
4. Value The value of opals varies greatly depending on their color, pattern, and clarity. Black opals are among the most valuable, while white and crystal opals are also highly prized. The play-of-color significantly affects the stone’s price, making opals one of the more valuable gemstones in the market.
Understanding Opalite
1. Man-Made Creation Opalite is a man-made glass product, often created to mimic the appearance of opal. It is sometimes mistakenly referred to as “opalite opal” or “opal moonstone,” but it does not share the natural formation process of genuine opal.
2. Physical Properties Opalite is typically clear or milky in appearance and can have a slight iridescence. Unlike natural opal, it does not display a natural play-of-color but can show a blue or multicolored sheen under certain lighting conditions. Its chemical composition is much simpler than that of natural opal, being primarily composed of silicon dioxide.
3. Uses Opalite is used in various forms of jewelry, including beads, pendants, and earrings. It is popular in metaphysical circles for its purported ability to improve communication and stabilize mood swings. Additionally, due to its affordability and ease of production, opalite is often used in decorative items and crafts.
4. Value Opalite is significantly less expensive than natural opal. As a synthetic material, its value is determined by its craftsmanship and aesthetic appeal rather than rarity or natural beauty. It is widely available and considered a budget-friendly alternative to opal.
Key Differences Between Opal and Opalite
1. Natural vs. Synthetic The most fundamental difference is that opal is a naturally occurring gemstone, while opalite is a synthetic, man-made material. This difference in origin affects everything from their physical properties to their value.
2. Play-of-Color Natural opals exhibit a unique play-of-color, making them highly sought after. Opalite, on the other hand, may show a sheen but lacks the true play-of-color seen in opals.
3. Physical Composition Opals are composed of hydrated silica with a complex internal structure that causes light diffraction. Opalite is primarily made of silicon dioxide and does not have the same internal structure, resulting in different optical properties.
4. Value and Rarity Opals are valued based on their rarity, color, pattern, and clarity. High-quality opals can be quite expensive. Opalite, being synthetic, is less valuable and widely available, making it a more affordable option for consumers.
Choosing Between Opal and Opalite
When deciding between opal and opalite, consider the purpose of the purchase. If you’re looking for a valuable, naturally occurring gemstone with unique optical properties, opal is the clear choice. However, if you need an attractive, budget-friendly option for jewelry or decoration, opalite serves as a suitable alternative.
Understanding these differences is crucial for collectors, jewelers, and anyone interested in gemstones. Whether you prefer the natural allure of opal or the manufactured beauty of opalite, both have their unique charm and uses.

Conclusion
In conclusion, while opal and opalite may appear similar at first glance, their differences in origin, physical properties, and value make them distinct. Opal, with its natural formation and mesmerizing play-of-color, stands as a valuable and highly prized gemstone. Opalite, although synthetic, offers an affordable and attractive alternative for various uses. By understanding these differences, you can make an informed decision based on your needs and preferences.
