When it comes to gemstones, sapphires are renowned for their stunning beauty and vibrant colors. But did you know that some sapphires have the remarkable ability to change color? These unique gems, known as natural colour change sapphires, are a true marvel of nature. In this blog post, we will explore the science behind natural colour change sapphires and how to authenticate their authenticity.

What Causes the Colour Change?

The mesmerizing colour change in sapphires is due to the presence of certain trace elements within the crystal lattice. The most common elements responsible for this phenomenon are chromium, iron, and vanadium. These elements interact with the crystal structure of the sapphire, causing it to exhibit different colors under varying lighting conditions.

How Does the Colour Change Occur?

The colour change in sapphires is a result of a phenomenon called pleochroism. Pleochroism refers to the ability of a gemstone to display different colors when viewed from different angles. In the case of natural colour change sapphires, the gemstone will appear blue or violet under natural daylight and shift to a purple or reddish hue under incandescent lighting.

Authenticating Natural Colour Change Sapphires

Due to their rarity and unique properties, natural colour change sapphires are highly sought after by collectors and gem enthusiasts. However, it is essential to ensure the authenticity of these gemstones before making a purchase. Here are a few key factors to consider:

1. Origin

Natural colour change sapphires are primarily found in Sri Lanka, Madagascar, and Tanzania. These regions are known for producing high-quality gemstones with exceptional colour-changing properties. Be sure to inquire about the origin of the sapphire to determine its authenticity.

2. Certification

Always insist on a reputable gemological certificate from a recognized laboratory. This certificate will provide detailed information about the gemstone's characteristics, including its colour change properties. Look for certifications from laboratories such as GIA (Gemological Institute of America) or AGS (American Gem Society).

3. Color Consistency

Examine the sapphire under different lighting conditions to observe its colour change. A genuine natural colour change sapphire will exhibit a noticeable shift in color, typically from blue to purple or violet to reddish-purple. The transition should be smooth and consistent.

4. Price

Natural colour change sapphires are relatively rare and valuable. If a sapphire is being offered at an unusually low price, it is essential to exercise caution. Genuine natural colour change sapphires command a higher price due to their scarcity and unique properties.

Conclusion

Natural colour change sapphires are a true wonder of nature, captivating us with their ability to transform their hues. Understanding the science behind their colour change and knowing how to authenticate their authenticity is crucial for both collectors and buyers. By considering factors such as origin, certification, color consistency, and price, you can ensure that you are acquiring a genuine natural colour change sapphire that will be cherished for generations to come.
