About Color Change Gemstones
Color-change gemstones in action are an amazing sight. Outside, in normal daylight, they may look green, blue, yellow or whatever color they may be but take them indoors and they will change color to red, orange, purple or any one of a myriad of colors.
There are very few gemstones with this color-change ability. They all have subtle differences in color and some even have the ability to change not only under different sources of light but also at different times of the day!
We have several great examples of color change gemstones including Diaspore, Fluorite, Garnet, Sapphire and most recently, the spectacular Hyalite Opal.
But how does this happen?
Imagine you are looking at a red apple. What we see when we look at an object is reflected light so waves of all colors hit the apple and all the colors are absorbed by the apple except red which reflect back so the apple looks red.
Different light settings can affect what colors we see. A blue gemstone viewed by candle light will look different to one seen in sunlight. Candle light is rich in red wavelengths but poor in blue. Daylight contains more blue and green light and less red light, incandescent light has more red light and less blue and green light.
The special chemical make-up and crystal structure of certain rare gemstones can cause an unusual phenomenon known as color change gemstones.
