Cat’s eyes are genuine rarities which are found only in a few deposits in the world, together with other varieties of chrysoberyl. One can hardly imagine that a gemstone could wink like the eye of a cat in such a remarkably genuine way.  handmade jewelry

Is it magic, or Nature? What is it that causes this irresistibly beautiful show of light?

Scientists have discovered that very fine inclusions, deposited in the stone, are responsible for this fascinating phenomenon. The incident light is reflected off them, so that a bright strip of light appears, running perpendicular to the inclusions, similar to the eye of a feline predator.

When the stone is turned, this strip seems to glide away across the surface of the stone. In technical terminology this phenomenon is known as ‘chatoyancy’, which comes from the French ‘chat’ (for cat) and ‘oeil’ (for eye). Whilst chrysoberyls lacking the cat’s eye effect are mostly faceted, cat’s eyes are always cut into cabochons, since only tall, rounded shapes render the line of the eye properly visible.

Cat’s eye, with its hues ranging from honey-colored to mint green, is a popular gemstone. In general, the value of a cat’s eye – as with other gemstones – depends on its quality, that is to say its beauty, color and attractiveness, the depth of the color and its transparency. Fine cat’s eyes should be of a distinctive color and be as transparent as possible. The most popular ones are those of a beautiful honey yellow and those with fine green tones.wholesale jewelry
