Curiosities of zodiac
Zodiac is the tanzanite, a thousand times rarer than the diamond. This hydrated aluminium and calcium silicate rich in chromium and strontium was discovered 30 years ago after a fire broke out in Kilimanjaro (Tanzania). It is believed that the period of exploitation of this very rare dark blue stone will be only 15 years. It is extremely limited the production of the gem, and as such of the jewels that treasure it, arriving to contribute a little more than 20 million dollars a year to Tanzania for its raw export; However, for an idea of the value of everything that surrounds tanzanite, it is considered that the trade around the gems already carved amounts to 500 million dollars. Not for pleasure the government of that African country has just created a law that prohibits the export of uncut stone.
Semi precious stones associated with the zodiac:
Semiprecious stone of greenish yellow colour, also known in the past as chrysolite, this refers to zodiac today in disuse. It has much more hardness than beryl and is widely used in jewellery. There is a stone of about 50 carats in the British Museum of Natural History. Its name comes from the Greek, which means golden beryl, and has a hardness of 8’5 on the Mohs scale.
- Citrine is also called citrine: It is another variant of quartz, but of lemon yellow colour and with its same scale of hardness, 7 Mohs. Its name comes from the French citron. Formerly, it had come to be called “quartz topaz” because of its resemblance to topaz, but we must make it clear that they are two completely different stones.
- Chrysoprase: Also known as chrysophora or lacewings. A variety of agate (chalcedony) with an intense bottle green colour. It is the most valued agate of all those belonging to the Chalcedon family. Its attractive green colour is due to nickel. Very popular in ancient Greece as a curiosity, to say that Alexander the Great always wore an envelope before entering battle. Currently, it is used as a substitute stone for the emerald, due to its colour and low cost compared to this one. It has a hardness of 7 on the Mohs scale.
- Cornelian: Orange-red agate of the chalcedony family. The one of brown tonality is called sardonia. Its high popularity is in some way related to the Muslim prophet Muhammad since he wore a ring of carnelian. Currently, it is back in fashion in Italian jewellery. It has a hardness of 7 on the Mohs scale.
- Quartz: Also called rock crystal, its virtue is its transparency and low cost. Very used in high imitation jewelery and also in jewelery, rock crystal is, in short, crystal clear crystallized rock. From the Greek krysallos, which means transparent ice, comes its name of rock crital. And referring to quartz, its slang comes from a German word dating from the fifteenth century. Its formation is a consequence of the slow crystallization of the residual magmas. It has a hardness of 7 on the Mohs scale.
- Smoked quartz: Also called fume quartz and incorrectly called topaz until recently smoke, since both have very different characteristics. Composed of silica, it comprises several shades of brown, from light to very dark. It’s very dark brown variety is called morrion. It has hardness on the Mohs scale of 7.
- Spinel: Its most important property is its great resemblance to the ruby. It can have several colours, from white to blue, passing through green, although the most appreciated is the red stone magnified by iron oxide in combination with magnesium. There is, however, a rare variety of cobalt blue spinel much appreciated. Its name comes from the Latin which means spine, in reference to its sharp crystals, since it normally occurs in an octahedral form. As a curiosity, to know that it has been confused in antiquity thousands of times with the ruby; proof of this is that many of the British Crown jewels considered, in the past, as rubies are, in reality, spinels.
