Spinel gemstones - Available in many different colors!
The Spinel is a gemstone that is usually associated with men, thanks to its strong and robust characteristics. For example, in the battle of Agincourt, fought in 1415, King Henry V, was struck in the head by a battle axe, and his life was saved by the Black Prince´s ruby, which was set in the helmet. The spinel is a strong stone, and the strength surpasses even that of the metals in which it is set. Over the centuries, people have mistaken spinels for rubies, and the converse is also true. You can imagine how shocked the queen on England was, when she got the news that the ruby in the crown jewels, which she loved so much, was not actually a ruby, but a spinel. You would have surely hated to be the person who delivered this bad piece of news. The Black Prince´s Ruby, earned itself a place in history, and is now placed in the British Imperial State Crown. Oddly enough, even Henry V though that the stone was a ruby, but it turned out to be a spinel weighing in at 170 carats.
Some interesting facts about spinels

They have the same beautiful attributes that mesmerize the eyes, and their structure and chemistry is the same; both even get their red color from the presence of chromium. However, the one distinction that sets them apart is the fact that spinels are softer than rubies on the Mohs scale. A spinel has a value of 8 while a ruby has a value of 9. The spinels have a pinkish fluorescence when they are viewed in natural light during the day, and they also have a lower refractive index, as compared to rubies.

The funny thing, though, is the fact that the red spinel is rarer than the ruby; however, they have one thing that makes them as popular as rubies; they are found in larger sizes. In ancient history, the large red spinels were known as the Balas Rubies, and they got this name because they were mined from the Northern Afghanistan region of Badakshan, which is still mined for gemstones. In history, no other region has produced bigger spines than this one. The stones mined from these mines were owned by some of the most renown historical characters; Peter the Great from Russia, Henry VIII of England and the Mongol Conqueror.
The naming of spinels
The crystals of a spinel are shaped like the thorns of a red rose bush, and the name is thought to have been derived from the Latin word Spina, which means Thorn. Another reason why the name was thought to be apt, was the fact that the vivid red colors resembled that of the roses found in the English Rose Garden. It is the impurities in pure spinel, which is white, which gives it the various colors that gemstone lovers adore. The main elements which provide these colors are Cobalt, Chromium, Vanadium, and Iron.
