A Little History

The history of Hyalite Opal dates back to ancient times. It is believed to have been first discovered in the Opal Mountain range in Slovakia during the medieval era.

The name “hyalite” is derived from the Greek word “halos,” meaning “glass,” due to its glass-like appearance. It was highly valued by ancient civilizations, including the Romans, Greeks, and Egyptians, who considered it a symbol of purity and hope.

Properties and Characteristics

Hyalite Opal is primarily composed of silica and contains a high water content, which contributes to its unique optical properties.

It is usually colorless or white, but it can exhibit a range of vibrant colors when exposed to ultraviolet light. Under normal lighting conditions, it may appear translucent or slightly milky.

However, when illuminated with UV light, it radiates a captivating greenish-blue glow, often accompanied by flashes of yellow, orange, and red. This phenomenon, known as fluorescence, adds to its allure and distinguishes it from other opals.

Uses of Hyalite Opal


Hyalite Opal is a popular choice for jewelry due to its captivating colors and unique fluorescence. It is often cut into cabochons and beads or carved into intricate shapes to showcase its beauty.

Hyalite Opal jewelry pieces, such as pendants, earrings, and rings, make stunning and eye-catching accessories that complement any outfit.

Other Fascinating Information

Unlike other opals, Hyalite Opal does not contain a distinct play of color. Instead, its beauty lies in its fluorescence and vivid colors under UV light.

The fluorescence of this gemstone is attributed to the presence of small amounts of uranium, which causes the gemstone to emit a bright glow when exposed to ultraviolet light.
