About Star Ruby Gemstone
Star ruby is the red to a pinkish red variety of the Corundum mineral group, Ruby is thus named because of its red color (Latin-ruber), The name corundum is the Sanskrit word kuruvinda. The red color variety within each individual deposit, so it not possible to determine the source area from the color. The designation €œBurma ruby€ and €œsiam ruby€ are therefore strictly erroneous, and refer more to quality than origin. The most desirable color is the so-called €œpigeon€™s blood,€ pure red with a hint of blue provides the color is chromium, and in the case of brownish tones,iron is present as well. As a rough stone, ruby appears dull and greasy, but, when cut, the luster can approach that of Diamond. Heat treatment is commonly used to improve the color. Ruby is the hardest mineral after diamond. However, the hardness varies in different directions. Ruby has no cleavage, but has certain preferred directions of parting . Because of brittleness, care must be taken when cutting and setting. Inclusions are common. They are not always indicative of lower quality but shows the difference between a natural and a synthetic stone. The type of inclusion (minerals, growth, structures, canals, or other cavities) often indicates the source area.
Ruby is the best known and most highly valued gemstone and is one of the top four gems (Diamond, Sapphire, Ruby, and Emerald) in popularity. This is mostly due to its beauty, intense color and toughness in jewelry. Ruby may show asterism (seen as star stone) when cutting as the cabochon. With a Moh€™s hardness of 9.0 and no cleavage, it is a very durable gem for jewelry. Ruby€™s red color is caused by minor amounts of trivalent Chromium (Cr) replacing Aluminum (Al) in the crystal structure. Pure Cr2O3 occurs in nature as the mineral Eskolaite, which is green.
Ruby is available from many locations around the world. Some of these locations such as Burma, Ceylon, and Madagascar, are well known for their fine Rubies.

I should be incapable of drawing a single stroke at the present moment; and yet I feel that I never was a greater artist than now.
Like these sweet mornings of spring which I enjoy with my whole heart.
When, while the lovely valley teems with vapour around me, and the meridian sun strikes the upper surface of the impenetrable foliage of my trees, and but a few stray gleams steal into the inner sanctuary, I throw myself down among the tall grass by the trickling stream.
A wonderful serenity has taken possession of my entire soul.
Authorities in our business will tell in no uncertain terms that Lorem Ipsum is that huge, huge no no to forswear forever. Not so fast, I'd say, there are some redeeming factors in favor of greeking text, as its use is merely the symptom of a worse problem to take into consideration.
Safe delivery, ensures the movement of goods in a short time.
You begin with a text, you sculpt information, you chisel away what's not needed, you come to the point, make things clear, add value, you're a content person, you like words. Design is no afterthought, far from it, but it comes in a deserved second. Anyway, you still use Lorem Ipsum and rightly so, as it will always have a place in the web workers toolbox, as things happen, not always the way you like it, not always in the preferred order. Even if your less into design and more into content strategy you may find some redeeming value with, wait for it, dummy copy, no less.
