• Updated On Mar 18, 2020

Gemstones, both precious and semi-precious have allured the people for ages. Some were in demand because of their striking beauty while others were preferred for their amazing healing energies. The world of gemstones is marvellous. There are around 200 varieties of gemstones that exist today and in these 200 varieties, there are a few which are actually considered the rarest and beautiful gemstones of the world.  Want to know about them?
 
Black Opal gemstone: Opals are usually creamy-white in colour with rainbow coloured inclusions that reflect the light as the stone is moved. But have you heard about black opals? Black opals are very rare. Almost all of them are found in mines in the Lightning Ridge area of New South Wales in Australia. The darker the background of the opal, the better the inclusions will reflect the light. The most valuable black opals till date is “Aurora Australis.” It was uncovered in Lightning Ridge in 1938 and is especially admired due to its large size and intense colouration. The Aurora Australis opal weighed 180 carats and when valued in 2005, it came about $763,000.
 
Grandidierite gemstone: Grandidierite was discovered in 1902 in Madagascar by French mineralogist, Alfred Lacroix. He named it in the honour of French explorer, Alfred Grandidier who was an expert on Madagascan natural history. The blue-green gemstone is found at a number of places but the gem-quality has so far been fetched from Madagascar and Sri Lanka only; thereby making it the rarest gemstone. The Grandidierite gemstone is translucent in a maximum of cases but they are also found as transparent (the rarest and most valuable type of Grandidierite). Once when transparent Grandidierite was unearthed, it was understood to be some another mineral. Later when experts exposed about its characteristics, it was concluded that it is a Grandidierite and was thereby sold for an undisclosed amount. IMAGINE!
 
Alexandrite gemstone: What makes alexandrite so beautiful and in high demand is its colour-changing capability. The stone appears blue-green in sunlight and when it is under incandescent light, it becomes red-purple. The degree of colour change in alexandrite varies from stone to stone but yes the ones which clearly demonstrates the colour change are regarded as the most valuable ones. The stone was discovered in 1830 in the Ural Mountains in Russia. The largest of alexandrite found up till date is of 65.08 carats otherwise the majority of them are under a carat. The value of the gem which is under a carat is $15000 each and the one larger than that, costs around $70,000 per carat.
 
Paraiba tourmaline gemstone: Tourmalines come in various colours in Brazil but the one with the bright turquoise hue is very rare and known as Paraiba tourmaline. The Paraiba Tourmaline was discovered in 1987 by Heitor Dimas Barbosa who firmly believed that something special is hidden under the hills of the Brazilian State of Paraiba. The stone is so rare that only one stone is mined for every 10,000 diamonds.
 
Benitoite gemstone: Benitoite is the gemstone that is only mined in one small area of California, near San Benito River. (the name of the stone comes from here) The stone has a deep blue colour which reflects interesting qualities when caught under UV light. The fact that makes this stone so rare is the closing of the mines near Benito River. Now it is extremely difficult to find a good-quality benitoite stone. In case if you find one, remember, this stone can fetch up to $10,000  a carat.
