Tourmaline is the birthstone of October with a hardness of 7-7.5.
The name originates from the Sinhalese (Sri Lanka) word tura mali which translates to ‘the stone of mixed colours’ due to the vast array of colours which makes it considered the most colourful of gemstones.
It was believed to have been discovered in the 1500s by Brazilian conquistadors, but it was in the 1800s that scientists discovered that Tourmaline was its own sort of mineral.
Important deposits are found in Sri Lanka, Afghanistan, Brazil and Mozambique.
Scientifically, Tourmaline is not a single mineral, but a group of minerals related in their physical and chemical properties; which is often the cause of many different colours.
Tourmaline has a rich history and a magical legend depicting that the gemstone passed through a rainbow on its way to Earth, giving an array of colours.
Black to bluish-black, dark brown to medium brown, yellow, dark blue to neon blue, lime to dark forest green, red to reddish purple, pink, and colourless.
Clarity is an important aspect of Tourmaline, as it can actually be found as transparent as a Diamond.
Many stones can even change colour when viewed at different angles.
Rubelite Tourmalines have vivid colour ranges from purplish-pink to purplish-red, and are well known for maintaining their colour under different lighting. Only the most saturated and vivid colours are given this name with the most saturated and redder colors being the most valuable.
Paraiba – the rarest Tourmaline
Named after the region of Brazil where it was first discovered, it is the rarest most valuable of Tourmalines. To put their rarity into perspective, one Paraiba is mined for every 10,000 Diamonds. Due to the trace element copper, colours can range from turquoise to majestic blue-green, but it is the incandescent glow from within that appears to light up the stone.
Bi-Colour & Tri-Colour
We absolutely love that some stones display two distinct colours giving them the name ‘bi-colour’ and making them sought after for their unique combinations. But our most favourite is the Watermelon Tourmaline having three colours in one and getting its name by looking exactly like sliced watermelon (yum).
Amazing electric blue colour resembling the deep blue colour of the ocean, Indicolite’s colours often have green as the secondary colour. This results in intriguing gemstones. varying from deep blue to turquoise.
As the name suggests traces of chromium and vanadium are responsible for this amazing forest green colour. Only found in Tanzania alongside of Tanzanite and Tsavorite, it’s strong dichroic properties make these gems extremely bright.
Tourmalines are a softer gem and because of that they require a little bit more TLC.
Avoid wearing them while doing heavy work, at gym or gardening (we strongly advise to remove them). Like all coloured gems, more regular cleaning will keep them clean.
