Opal is a mesmerizing gemstone that has captivated people for centuries. Its unique play of colors and iridescence make it a highly sought-after gemstone in the jewelry industry. But did you know that the brightness of an opal can significantly impact its value? In this blog post, we will explore the effect of brightness on opals and how it can unlock their true value.
What is Opal Brightness?
Brightness refers to the intensity of light reflected from the surface of an opal. It is determined by the opal's internal structure and the arrangement of its silica spheres. Opals with a high brightness level exhibit a vibrant play of colors, while those with low brightness may appear dull or lackluster.
How is Opal Brightness Measured?
Opal brightness is measured on a scale of one to five, with one being the brightest and five being the dullest. This scale, known as the Brightness Scale, was developed by the Opal Association of Australia to provide a standardized method of assessing opal brightness. We work off B1 to B10 range but based on same original scale.
The Effect of Brightness on Opal Value
The brightness of an opal has a significant impact on its value. Opals with a high brightness level are considered more desirable and valuable in the market. This is because a bright opal exhibits a vibrant play of colors, which is the defining characteristic of opals. The colors seem to dance and move within the stone, creating a mesmerizing effect that is highly sought after by collectors and enthusiasts.
On the other hand, opals with low brightness may appear dull and lack the vibrant play of colors. These opals are generally considered less valuable and may not fetch a high price in the market. However, it's important to note that opal brightness is just one of the factors that determine its value. Other factors, such as color, pattern, and clarity, also play a significant role in determining the value of an opal.
How to Enhance Opal Brightness
If you have an opal with low brightness, there are a few steps you can take to enhance its brightness and unlock its true value:
- Polishing: A professional opal polisher can help bring out the brightness of an opal by removing any surface imperfections and enhancing its luster.
- Lighting: Proper lighting can make a significant difference in the appearance of an opal. Natural sunlight or a bright white light source can help bring out the colors and brightness of the stone.
- Cleaning: Regular cleaning can help maintain the brightness of an opal. Use a soft cloth and mild soap to gently clean the surface of the stone, removing any dirt or debris that may be dulling its brightness.
By following these steps, you can enhance the brightness of your opal and unlock its true value.
In Conclusion
Brightness plays a crucial role in determining the value of an opal. Opals with high brightness levels are considered more valuable due to their vibrant play of colors. By understanding the effect of brightness on opals and taking steps to enhance it, you can unlock the true value of your opal and enjoy its mesmerizing beauty for years to come.
