In today's day and time, there will be hardly anyone who does not use smileys as an intrinsic part of their conversation. And talking of smileys, have you ever wondered why they are always yellow in colour?

Moonstone is perhaps one of the prettiest gemstones available and its rather distinct name has an interesting story behind it. It is believed that the gemstone is named so because the ancient Romans believed that the shimmering rock was formed from frozen moonlight and named it moonstone. It is one of those gemstones which is rarely found in its true form and is becoming rarer by the day. Originally, the moonstone is a perfectly clear and colourless body with a blue sheen but the rainbow moonstone found in India and Madagascar ranges from pink to purple, to yellow, peach and blue in colour.

It is not only a lovely looking stone but is also known to enhance happiness and prosperity among its users.

When we think of the colour green, the first image that comes to our mind is of lush green foliage, which is perhaps one of the most beautiful sights that nature has to offer. The colour green is not restricted to only flora and fauna in nature and a variety of animals of green colour are a sight to behold too. One such spectacular example is the garden insect. This insect has a shiny jewel like appearance and an oily exterior surface, which makes its green hue glow. On a closer inspection, you can see that it is not only green but a dazzling blue-green colour which adorns its body.

The inevitable sign marking the arrival of spring is the sight of blossoming trees and the dull colours of winter giving way to the cheerful colours of spring. In Denmark, though there is more to spring than simple blossoms all around, around half an hour before sunset approximately more than a million European starlings gather together in the sky to form some amazing formations. This phenomenon is known as the Black Sun in Denmark and can be observed during early spring throughout western Denmark. These starlings spend the entire day gathering food from the meadows and as soon as the day begins to set, they fly into the sky to make these beautiful formations.
