NEW ARRIVAL *** MOST AMAZING COLOUR CHANGE GARNET IN SOUTH AFRICA

        ***AWESOME COLOUR CHANGE  *** GEMSTONE RING   Defining Color Change In Color Changing Gemstones Did you know there are such things as color changing gemstones? Some exquisite gemstones change color under different lighting sources from natural sunlight to florescent or different internal lights. These color changing gemstones come from many different families of minerals including Alexandrite, Garnets and some Sapphires. First let me point out that color change is defined by what you see between natural and artificial light. If you think about it for a moment, it will be obvious. Electric lights have only been around for a bit over a century, but the color change phenomena in color changing gemstones has been know for much longer. Originally, it was defined as the difference people saw between sun light and fire light, be that from a candle, oil lamp, or whatever. As incandescent light became common, the effect was the same as comparing sun light with fire light. so the definition was modified to be a comparison between natural and electric lights. Below are pictures of a Garnet. This is one of the most widely available color changing gemstones on the market today.   So why is it that only a few gemstones exhibit these dramatic color changes, since nearly all gemstone color depends on the nature of the illumination? The answer is that these color change gems have two, approximately equal-sized transmission windows. A red gemstone appears red because it absorbs all frequencies of light except for red. A gemstone that absorbs all frequencies except for blue and red light will appear blue when the light is rich in blue wavelengths (e.g., fluorescent light) and red when the light is rich in red wavelengths (e.g., incandescent lighting).  The Physics behind Color Changing Gemstones The actual mechanism behind color changing gemstones is quite simple. Every light source has a different fingerprint. That means that visible light can be made up of many different wavelengths that show different colors   In the image above it is easy to see that noon sunlight (the yellow line) has a relatively flat line that contains almost every color.   STONE SIZE: FACETED PEAR SHAPE 13 X 10 MM METAL: SOLID.925 STERLING SILVER  RING SIZE: 9 MORNING/ DAYLIGHT OR BRIGHT NIGHTLIGHT HOT PINK TAKEN WITH MY PHONE CAMERA   LATE AFTERNOON   LOW LIGHT/ EVENING LIGHTING TURNS TO AMETHYST GREEN PAYMENT WITHIN 48 HRS UNLESS OTHERWISE ARRANGED WITH SELLER
