Coloured gemstones are a brilliant and amazing gift of nature. Although colour saturation, clarity, and brightness are frequently appreciated characteristics of coloured gems, not all gemstones are made equal. Some coloured gemstones, even those in the same family or species, stand out from the others due to extraordinary qualities or effects, known as phenomena. Many people are familiar with some of these phenomena and can easily identify labradorescence in labradorite, play-of-colour in opal, and chatoyancy in stones like sapphire and tourmaline.

1. Alexandrite
Any discussion of gemstones with variable colour must include alexandrite. When it comes to naturally occurring specimens, alexandrite is one of the most expensive colour-shifting gemstones. However, synthetic alexandrite is frequently inexpensive and has a different premium price tag than its natural cousin.
Since that is the hue you'll see in actual sunshine, the base alexandrite colour is typically described as a mossy, green colour that is slightly bluish. However, when viewed in incandescent light, the stone changes colour, frequently taking on a faint reddish or raspberry tinge. As a result, some people compare alexandrite to an emerald by day and a ruby at night. Because green and red are complementary colours, the colour change in alexandrite is one of the most obvious and striking. Check our website for these colour-changing gemstones.

2. Sapphires
A colour-shift sapphire is not typically considered when considering a colour-changing gemstone. This is primarily because colour-changing sapphires are extremely uncommon and not readily available on the market. Additionally, due to their rarity, they are exceedingly expensive colour-changing gemstones.
A sapphire that changes colour in natural light is a traditional blue sapphire. The colour changes to purple when the gemstone is exposed to artificial lights. Each stone changes differently. In natural light, the colour change in some sapphires is exceedingly minor, showing only a faint purple hue. Others find it incredibly unique, virtually turning a sapphire into a vivid purple amethyst in the correct sunlight.
3. Andesine
A feldspar mineral has the potential to change colour andesine. Not every stone will undergo a colour change. Instead, they usually have rather consistent colorations: red, green, yellow, or pale yellow. Depending on the sunlight and position, andesine's natural colours can be green and red in the stone. Because of this, in faceted andesine, certain segments could appear to stay green while others display earthy red tones. The colour changes you occasionally see can also alternate between violet, purple, and green. Again, if the andesine is faceted, it is easiest to see the many colours.
4. Diaspore
The diaspore's colour changes are quite remarkable. The colour is often lime green or kiwi green in bright light, similar to what you might see with peridot. The colour changes in incandescent light, potentially becoming an earthy pale yellow but typically falling into the champagne range. It can also have a little purplish-pink colouring in very low light.
Turkish gemstones that shift colour include zultanite. Although it is sold under a different name, the gemstone zultanite is diaspore. In other words, the zultanite colour change is exactly as previously explained.
5. Spinel
While spinel isn't renowned for having a drastic change in colour, some specimens do. Typically, deep blue spinel is the most typical colour for this. When seen in indoor light, the tint of blue in those may begin to veer towards purple. Colour-change spinel has the advantage of not necessarily being the most expensive variety of gemstones but costing more than others. Instead, it falls somewhere in the middle, making it a reasonably priced stone that changes colour. You can buy these types of Authentic natural gemstones.

6. Fluorite
Many people think any colour-shifting features you notice are natural because fluorite comes in various colours. Fluorite does occasionally have the ability to change colour on its own, but this is usually quite uncommon. Instead, that characteristic is frequently enhanced in colour-changing fluorite gems. When fluorite is exposed to radiation, a blue gemstone might appear to change colour to purple in the correct lighting.
Fluorite that changes colour occasionally comes in pieces with varying tones throughout the stone. This can change the appearance of colour depending on how it is faceted because the other colour isn't visible from every angle.
7. Topaz
Topaz occasionally displays a strong fluorescence that allows it to change colour. However, this is normally relatively faint and is mainly noticeable under blue UV light wavelengths. For instance, a blue or colourless topaz at a long wavelength UV may show a little yellowish or greenish hue.
Some topaz is also exposed to radiation to change the underlying hue or increase the likelihood of a colour shift under particular lighting circumstances. You'll also see that topaz and other gemstones have been given coatings that display a wider spectrum of tones.
8. Garnet
If you have the appropriate specimen, garnet is another stone that changes colour in various lighting conditions. Depending on the light source, a colour-changing garnet may start reddish brown and transform to reddish-purple or pink under candlelight alone, or it may start as a bluish-green stone and turn purple. Others transition subtly from darker earthy reds to brighter oranges, truer or purple reds to raspberry pinks, or vice versa.
