About Tourmaline

Tourmaline is the rainbow kaleidoscope of the mineral kingdom. This wonderful gemstone comes in virtually every colour you can imagine with a range of subtle hues and variations that is astounding. Over the years tourmalines have become more and more highly sort after and appreciated for their magnificent colours, sizes, clarity and simple beauty. Beautiful tourmalines come from all over the world from countries such as Brazil, Afghanistan, USA and African nations like Namibia, Nigeria, Congo, Mozambique, Tanzania, and many more. It is truly a global gemstone and finds a home everywhere.

Photographing coloured gemstones is very challenging especially when trying to capture the beauty, richness and interplay of colours. As is true of all gemstones, Tourmalines really do need to be seen in the hand to fully appreciate just how wonderful and unique they are. Tourmalines in particular are often dichroic or trichroic meaning they exhibit different colours when viewed along the different axis of the gemstone, for example blue and green, or pink and red, and so forth. This interplay of colours is something that is almost impossible to capture in a static picture, but in the hand you will see something truly amazing and breathtaking... and mysterious. I have tried my best but the camera, lighting and my abilities can only do so much. Sometimes in pictures there might be certain subtle hues which appear that simply are not in the gem when viewed in the hand, or not as prominent or strong as the pics might suggest. However, I have found it to be true that if you like the picture you will love the gem.

I am able to offer the public one of the finest curated selections of tourmalines in Sydney.
The tourmalines shown here are just a very small selection of what is available.

This gem is really one of those stones that you've got to see in the hand to truly see it's full beauty. It is a fine tourmaline with a blend of light pink and green. The pictures do not do the gem any justice and it is much nicer in the hand. The gem is more pink and green and doesn't have the grey that is in the pics. Very hard to photograph these light coloured tourmalines. The design is a high dome and the gem has great scintillation and sparkle. It is a stunning tourmaline and would make for a great cocktail ring.

In the hand this tourmaline gem is an absolute stunner. It is a bright light minty green and is much much better then the pics suggest where it seems to be darker. These lighter hued tourmalines are very hard to photograph but I've tried my best but they never really fully capture a gem. It is an ideal size for an everyday ring.

This is one of the most beautiful tourmalines I've seen for a while and defintely has the "it" factor. The blue hue is just incredible and much much nicer then the pics suggest. The gem was a tricky one to photograph and I know I haven't fully captured it's beauty. The blue is that wonderful Caribbean blue and reminds me of really nice Paraiba tourmaline. It is an exceptional gemstone and one that I highly recommend.

This is a very fine cuprian mint green tourmaline from Mozambique. Cuprian means that the tourmaline is copper-bearing and is very similar in nature to the highly prized Paraiba tourmaline from Brazil which is also copper-bearing. These cuprian tourmalines are very highly sort after, both for their colour and their rarity. They come in a range of colors, usually in the blue and green hues. This one is a very lovely minty green colour and it is an ideal size and shape for any jewellery setting.

Comments : Paraiba type tourmalines are a rare kind of tourmaline which are copper bearing. These fabulous tourmalines are found in only a very small number of locations, most famously Brazil and Mozambique. The copper is what gives these tourmalines the incredible neon like blues and minty green hues that make them so very highly sort after. This Paraiba type tourmaline is a very fine example and if you can imagine yourself up high gazing down on pristine Caribbean waters on a bright clear day, thats the colour of this wonderful gem. Superb!

Comments : There is truly a joy that I find everytime I look into a well cut, richly coloured gemstone, be it tourmaline, sapphire, ruby or any of the other myriad gifts of Mother Earth. This joy is always fresh and new, always with a sense of discovery and curiosity at what I will discover and see. I love the interplay of hues that come natural to gems such as tourmaline. They are wonderful and ever pleasing. This is one such tourmaline gemstone. Fine deep hues of blue and green coupled with the timeless cushion cut make this a superb gemstone.

Comments : Tourmaline is a gem that comes in almost every colour imaginable and often in breathtaking combinations. It is thought that the Dutch, importing it from Sri Lanka to Europe in the early 1700's gave it the Sinhalese name, Turamali, meaning "stone with mixed colors". Gems with two or three colors are much sort after, such as blue/greens, mint greens/clear, pink/greens and gold/red. For example, a certain mixture of colours is called watermelon tourmaline where, cut in a cross section, the outer rind appears green whilst the inside is pink. Pinks (intense hot pink and light bubblegum pink), reds and blues are the most desired colors. Some tourmaline gems are treated in order to improve their colour.

In the last 20 years tourmaline has gained great popularity among gem collectors and the gem buying public because of its beauty, availablity and myriad colors. It cuts a stunning gem and suits almost all design styles. Fine examples of tourmaline can be obtained in relatively large sizes though 2 - 10 carats is a popular size range. Tourmaline often has inclusions and eye clean gems are the most desirable. Tourmaline forms as beautiful long crystals and are a great favorite among mineral specimen collectors. This stone can also be found in alluvial deposits as water worn nodules.

A curious property of tourmaline is that when heated and cooled, or by applied pressure, it will become electrically charged (pyro and piezo electricty). The charged stone can attract pieces of paper and dust. It was also used to pull ash out of meerschaum pipes by the Dutch who understood this property of tourmaline. They called tourmaline "aschentrekker" (ash puller).

One thing that can affect the colour and arguably the "quality" and price of a tourmaline gem is if it has what's called a
closed "C" axis. What does this mean? Well, given a tourmaline crystal in its original shape, if you look down the crystal (as if you were looking down a metal pipe) and it appears black or very very dark, this tourmaline is said to be "closed", like pulling a curtain across a window. If you can clearly see down the crystal even though the colour may change slightly, eg. a pink tourmaline might look peachy down the "C" axis, it is said to be "open". When a tourmaline with a closed "C" axis is cut, the resulting gem will in all likelihood appear darkish, especially around the ends if it is a rectangluar design. All things being equal, an "open" gem should demand a higher price then a "closed" gem. You can see an example of an open "C" axis tourmaline in the rough here.
