Color change sapphires are unique and fascinating gemstone that displays a stunning transformation of color under different light sources. These rare gems have a rich history, and their origins can be traced back to ancient times. This blog post aims to provide an overview of color change sapphires and their characteristics.

What are Color Change Sapphires?

Color change sapphires are a type of corundum, the same mineral family as the traditional blue sapphire. What sets color change sapphires apart is their ability to display different colors under various light sources. The phenomenon is caused by the presence of certain trace elements in the crystal lattice structure of the sapphire.

The Color Change Phenomenon

The color change phenomenon in sapphires occurs due to the selective absorption of light by the trace elements present in the crystal lattice structure. The color change can range from blue to purple, green to yellow, and grayish-violet to pink, depending on the trace elements present. Color change sapphires can appear blue in daylight or fluorescent lighting and then transform into a purple or pink hue under incandescent light.

Examples of color-change sapphire jewelry are found in sapphire rings, earrings, necklaces, and bracelets. These pieces of jewelry are typically set in white gold, yellow gold, or platinum, to accentuate the color-changing effect of the gemstones.

The Rarity and Value of Color Change Sapphires

Color change sapphires are rare and valuable gemstones. Their rarity is attributed to the specific geological conditions required to form these unique sapphires. The value of color change sapphires is determined by the intensity of the color change, the clarity of the gem, and the carat weight.

How Colour Change Sapphires Differ from Alexandrites 

One unique aspect of color change sapphires is that they can exhibit a wider range of color change than Alexandrites. While Alexandrites typically exhibit a change from green to red or purple, color change sapphires can show a wider variety of color changes such as blue to purple, green to yellow, or grayish-violet to pink.

Additionally, while Alexandrites are known for their sharp color change, color change sapphires can display a more gradual or subtle change in color. Another difference is that color change sapphires are generally more durable and resistant to scratches and chips than Alexandrites.
