Loose Natural Color Changing Sapphires
What are Color-Changing Sapphires?
Color changing sapphires may not be as popular as the blue sapphires or rubies, but they are uniquely captivating and equally precious. Unlike traditional sapphires which are usually in a consistent color, natural color change sapphires change hues depending on the light source they are exposed to.
The science behind this is linked to the sapphire’s crystal structure made of trace elements such as chromium, iron, and vanadium. These elements interact with light in different ways which change the hues of the gemstone. In natural daylight or fluorescent lighting, color changing sapphires usually appear in blue or violet hues, which change to purple, pink or reddish-orange in incandescent or candlelight.
One of the earliest records of color changing sapphires is of the “Le Saphire Merveilleux” gemstone that was at the South Kensington Museum in London. Cherished for their ability to shift from a vibrant blue in daylight to a deep violet under artificial light, these gemstones served as a test of female virtue; the color change supposedly indicated if the wearer was unfaithful to their partners.
Varieties and colors of color changing sapphires
Blue to violet is one of the most common transitions among natural color change sapphires. These gemstones shift from a blue hue under daylight to a violet shade under artificial light. Another common transition is stones with yellow hues shifting to orange in a few hours under incandescent lighting.
While some color changing sapphires have such slight changes, some transition completely. One example is gemstones that appear green-ish under daylight or fluorescent lighting transitioning into a beautiful pink or a reddish-pink under incandescent lighting.
The transitions that are seen in these rare sapphires are similar to the transitions seen in Alexandrite. Like alexandrite, color changing sapphires shift from green-ish hues under daylight to purple-ish or red-ish purple hues under incandescent light. However, Alexandrites are a variety of the chrysoberyl mineral, completely different from color changing sapphires.
Regional differences in color changing sapphires
Depending on the country of origin, the transition styles of these sapphires tend to vary, producing distinctive color changing effects.
The Sri Lankan color changing sapphires usually appear in vivid blues or green hues under natural lighting, which then shift to pink, purple or reddish tones under artificial lighting. Madagascan color changing sapphires are among the most desired color changing sapphires for their intense and vivid color display, and these most commonly change from blue to violet or green to pink. Tanzanian color changing sapphires transition in a variety of stunning interplay. They appear pink-ish brown in daylight and transition to violet-red under incandescent light.
Treatments and Enhancements
How to select the perfect color-changing sapphire
- Color change intensity: The intensity of the color change is the most important factor when selecting your perfect sapphire. Gemstones with strong color transitions are rare and also are more valuable.
- Clarity and cut: The most common cuts for color change sapphires are oval, cushion, and emerald allowing excellent light reflection on these gemstones. When it comes to clarity, gemstones with eye-clean inclusions are ideal whereas stones with minor inclusions are also considered desirable.
- Carat weight and its impact: Usually, larger carat weights are valued for higher prices, however, other factors such as color change intensity and clarity of the gemstone take preference over carat weight.
- Natural vs treated stones: Natural gemstones change color organically while treated stones undergo processes to enhance their color and clarity. Unheated and untreated natural gemstones change color with great intensity making them very valuable to enthusiasts.
- How lighting affects appearance: These sapphires change colors under different lighting conditions. When choosing your perfect color changing sapphire, test the gemstone under different light sources from daylight to candlelight to determine the full range of transitions.
- Certification and authentication: The best way to ensure the authenticity and quality of a color changing sapphire is to obtain one from trusted jewelers with proper certification and authentication. Gemstone certification verifies their characteristics including color, clarity, treatments status among other details so buyers are fully aware of their gemstones.

In some cultures, color changing sapphires are believed to bring wisdom, protection, and good fortune to those who wear them. In holistic healing practices, color changing sapphires are closely associated with the throat chakra stimulating clear communication, creativity, and self-confidence.
In astrology, color changing sapphires are the planetary stone of Saturn, which signifies discipline, responsibility, and karma. While sapphires at large are preferred for their aesthetic beauty, such deeper symbolic significance and healing properties associated with these stones make color changing sapphires so much more appealing.
Care tips for color-changing sapphires
Sapphires are very durable gemstones, second only to diamonds. But they still need to be cared for, to maintain its shine and shape.
