Color change gemstones exhibit different colors under varying light sources, typically shifting between daylight and incandescent light. This phenomenon is caused by the way the gem's crystal structure absorbs light.
Which gemstones display color change properties?
Notable examples include Alexandrite, Color Change Garnet, Sapphire, and Diaspore. Alexandrite is the most famous, typically shifting from green in daylight to red under incandescent lighting.
Are all color change gemstones natural?
Not necessarily. While many are natural, some color change effects can be simulated in lab-created stones. Always check certification to confirm authenticity and origin.
How is the strength of the color change measured?
Color change is rated based on the degree of visual shift — strong, moderate, or weak. A strong change means the gemstone displays distinctly different hues in different lighting.
Why are color change gems more expensive?
Rarity and visual uniqueness drive the price. Natural stones with a strong and distinct color change, especially Alexandrite, are considered highly valuable.
Can color change gemstones be used in everyday jewelry?
Yes, depending on the gem’s hardness. Alexandrite and Sapphire are durable for daily wear, while softer stones like Diaspore require more care.
Are these gemstones certified?
At GemSelect, all color change gemstones are certified to guarantee their authenticity, natural origin, and the presence of color change properties.

Found a beautiful opal at a great price. I was not disappointed when it arrived. Even better in person.

I've made several purchases through GemSelect in the past, although not within the last six months. Their gems are always beautiful and I have never had an issue with their prices or their stones. Even when I'm not buying, I love scrolling through their website, which is very user friendly. I especially appreciate being able to change the listing order to your own liking, such as most to least expensive, largest to smallest, etc. As with most online orders, however, I think the shipping charges are not commensurate with the actual weight of the items shipped.

I love the quality, presentation and the price of the stones. I love the identification card - report they send with each stone.
