Cats? eyes are considerably larger and more round than those of a human in proportion to the rest of their body and this size and shape allows them to see things in conditions where there is very little light.
That is why they can easily wander around at night and capture their prey. If you are unlucky they might bring it back to show you in the form of bugs, birds, mice and all sorts of other creatures, that you really don't want to share your bed with in the middle of the night.
Cats will bring their capture in to show you when they are looking for some form of positive recognition and even though you might not want to see what they have caught, they should be congratulated for what they have done where possible.
Cat's eyesight only allows them to see clearly for a few feet but fortunately they have a keen sense of smell that can help them become aware of approaching danger.
Cats are also very sensitive to vibration and can ?feel? someone's presence before they can see them.
As cats get older they will tend to be less aware and will need additional care so that they don't get in trouble with dogs and other animals that they haven't noticed approaching them.
Cats are unable to rotate their eyes as much as humans and many other animals but they are a lot more flexible and can rotate their head a lot more and that more than makes up for any lack of movement in their eyes.
Cats are generally more attuned to movement and can find their prey a lot easier in the dark than when there is too much sunlight.
Taking care to look after your cats eyes is in your, and your cats, best interest.
Cats eyes and stars appearing in gemstones are still considered inclusions but of a unique type. While the presence of inclusions is often detrimental to the value and looks of gemstones, cats eyes and stars have the opposite effect. These may occur naturally or man-made but ultimately, they enhance the beauty of gemstones. Use the following tips when shopping for gemstones with stars and cats eyes.
What You Need to Know about Cats Eye:- Cats eye is a product of chatoyance or chatoyancy. It is an optical effect brought about by a certain light intensity emitting in a specified direction from the gemstones surface. Cats eye may either be produced by fibrous cavities or inclusions, such as the case of cats eye in chrysoberyl, or fibrous structures like cats eye in quartz.
The effects of chatoyancy can also be achieved in woodworking and providing products with 3D appearances.
Chrysoberyl This gemstone is arguably the most popular gemstone for its cats eye inclusions. Chrysoberyl is often mistakenly believed to be under the beryl group of stones. In truth, chrysoberyl is not part of the beryl group, but aquamarines and emeralds are. Chrysoberyl are mostly found in East Africa, Sri Lanka, and Brazil.
This gemstone registers the third highest rating in the Mohs Scale for naturally occurring stones. There are three types of chrysoberyl: alexandrite, the more common yellow chrysoberyl, and lastly cymophane or cats eye.
Common chrysoberyl is yellowish-green. It may be translucent or transparent. If it turns yellow and see-through, that is the time it can be used as a gemstone. Alexandrite, on the other hand, has colors varying from orange-yellow to red to emerald-green. It can display even other colors if seen under artificial lighting.
Lastly, there is cymophane or the chrysoberyl cats eye. Its name was derived from its similarities with a cats eye, showing a silk-like spread of light stretching from a light-green source.
Beryl Certain gemstones belonging to the beryl group can also display chatoyant features. This includes golden and green beryl, aquamarine, and emerald. The effects are, however, not as intense as those in chrysoberyl and therefore needs special mounting to strengthen the look and feel of its cats eye.
Quartz This is the most abundant mineral in the Earths crust. Not all of the minerals belonging to the quartz group are able to display cats eye on their surfaces. Those that can are rose quartz, citrine, smoky quartz, cats eye quartz, and amethyst. Some believe that cats eye quartz are able to help improve vision problems, self-healing, concentration, and psychic abilities, as well as provide better judgment.
What You Need to Know about Star Gemstones Stars in gemstones occur mainly because of asterism. It is another optical effect caused by a certain reflective portion of the gemstone. There are two kinds of asterism that occur in gemstones.
Disasters Stars appear when light is transmitted through the gemstone. It will only be visible, however, if light illuminates the gemstone from the back. Rose quartz exhibits this effect.
Epiasterism This occurs mostly with rubies and sapphires. Light this time is reflected on inclusions positioned parallel with each other.
Star gemstones come in a wide variety. For sapphires and rubies, there are yellow, purple, gray, black, blue, silver, white, and 12-ray stars. Burma and Sri Lanka are the top producers of star sapphires and rubies. Other gemstones with stars possibly appearing on their surfaces include sunstones, garnets, rutiles, quartz, diopside, citrine, moonstone, prasiolite, and chrysoberyl as well.
How to Shop for Star and Cats Eye Gemstones:-
Light A single light source like a candle, light bulb, or even sunlight is best used when judging the quality of stars and cats eyes in a given gemstone. This type of lighting will reduce chances of blurring and make it easier for you to determine the intensity of these much-coveted inclusions.
Distinction The appearance of the cats eye or star must be clearly distinct from the body of the gemstone.
Size How far does the star or cats eye extend? Bigger size is better, but some clients may prefer a more subtle effect.
Color More specifically, color for stars in gemstones differ. It is up to you to choose which appeals to you the most.
Lastly, remember that all gemstones with stars and cats eyes are cabochon cut to maximize their effects. Thus, viewing uncut gemstones will not yield accurate results.
