Coloured gemstones are the natural choice when it comes to designing fancy jewellery. But have you tried using a black jewel yet? If the answer is ‘no’, it’s time you did! Black jewels, which are known to form naturally within the earth, are a neutral shade like white stones, and can give your jewellery a much-needed “bang”, making you the cynosure of all eyes, regardless of the shade of clothes you are wearing.
Ready to find out more about which stones you can choose from, to transform your jewellery? Here’s the list of the Top Five choices – from the most expensive to the more pocket-friendly.
More expensive than even diamonds in terms of their price and value, black opals come in all colours – including black. Black opal is characterised by a dark body tone which can range from dark grey to jet black.
However, unlike ordinary opals, black opals have carbon and iron oxide trace elements present, which cause the unusual darkness of the stone. Because of their dark body tone, the rainbow colours in a black opal stand out much better than lighter opals. Australian black opals are the most valuable and widely known type of opal.
Contrary to popular belief, diamonds are not just white or colourless, but come in almost all colours including black. Called Carbonado – it is the toughest form of a natural diamond. These gems appear black due to various impurities that impart a dark colour to their appearance.
Needless to mention these stones are extremely hard to find and cost a lot more than traditional white diamonds. A large part of the global supply of these black beauties is found in alluvial deposits in countries like Brazil and the Central African Republic.
Beryl in its purest form is colourless and clear. It’s the inherent impurities present in this mineral that gives it colourful hues. Well-known varieties of beryl include gemstones like emerald and aquamarine.
While yellow and green beryl (emerald) are quite popular, red and black beryl are not found very easily and are known to be extremely rare. Mozambique and Madagascar are two countries where the black variety is mined in small quantities.
When one thinks of a pearl the image that comes to mind is of a magnificent, translucent white orb that glistens when held against light. But did you know there are black pearls too?
Black pearls are traditionally referred to as Tahitian pearls since they are primarily cultivated around the islands of French Polynesia, near Tahiti. Found inside the oyster Pinctada Margaritifera, a true black Tahitian pearl is extremely rare, and largely considered one of the most beautiful kind of pearl in the world.
Most Tahitian pearls that are identified as “black” are actually charcoal grey, silver, or dark green. Due to the variety of shapes and colors of the Tahitian pearl, it has been known to fit in any jewellery setting. The versatility and mixture of color give it its value.
Sapphire is the popular name for one of the varieties of the mineral ‘corundum’. Popular for their dark blue avatar, sapphires can in fact occur in a variety of different colours due to the presence of other chemical elements within its structure – including black and white.
A black sapphire is a nearly opaque stone whose dark contours appear to absorb all the light that enters the gemstone. This variety of sapphire is considered low grade and is hence quite affordable.
Black rocks are known to occur widely in the earth’s crust, and many of them although not in the precious or even semi-precious stones category still make their way into jewellery. A few examples being stones like: hematite, jet and obsidian.
Some of the other black rocks that are often used in jewellery making include: amphibolites, lodestone, tektite and lava.
