The Science Behind Blue Sapphire’s Stunning Color
With its rich, hypnotizing color, blue sapphires are some of the most popular gemstones around the world. What gives these gemstones their astonishing blue color? In this guide, we will analyze the chemical structure of a blue sapphire and the trace elements that determine its color. If you intend to buy a blue sapphire stone or want to learn more about premium quality blue sapphires, this guide is sure to help you value these stunning stones a lot more.
Why is Blue Sapphire Blue in Color?
A blue sapphire is formed from the mineral corundum which is made out of aluminum oxide (Al₂O₃). In its pure state, corundum is colorless. However, with the presence of trace elements such as iron and titanium, the light gets refracted in a way that the now-familiar blue color emerges. This phenomenon is known as the crystal field theory, as it describes the way that electrons absorb and reflect light in different radiations and results in the captivating blue shades that are desired in sapphires.
Shades of Blue Sapphire: What Determines the Color?
While blue sapphires may all be perceived as similar, they can differ greatly in hue; some may be a light cerulean while others could be a rich royal blue. This differentiation can be attributed to the following reasons:
- Trace Element Concentration - The concentration of certain elements such as iron and titanium directly correlates with the richness of the blue hue.
- Heat Treatment - A considerable number of sapphires are treated with heat to augment their color and help remove inclusions.
- Origin- Geographic location is greatly responsible for the unique color of a stone. Take Kashmir sapphires for instance; they are renowned for their velvety blue, while Ceylon sapphires offer the vibrant cornflower blue.
If one is interested in acquiring a premium blue sapphire gemstone, it is fundamental to keep in mind these nuances to guarantee the best standards of quality.
