Blue and green reigns supreme

Those of you who know me well know that I love tourmaline. Out of all gemstones, it is simply my runaway favourite, and I value it for its infinite variety; the colour range, the pleochroism, even the fantastic and fascinating inclusions. This is a fantastic 15.1mm round bluish-green tourmaline cabochon – yes it’s all the same stone in the slideshow above but what you are seeing is an example of that pleochroism I was referring to. Tourmaline is strongly pleochroic; that is to say that it absorbs different wavelengths of light depending on the direction of the rays. What that means in reality is that it will show different colours according to different viewing directions. You can see that in the stone above, which shows both green and blue colours, strongly. It’s an absolute beauty.

Now, tourmaline grows in an environment rich in liquids, which are often captured as inclusions during crystal growth. I wish I had a camera on my microscope as when I view this stone, I see a network of tiny thread-like cavities running all over the stone. They are really fascinating and beautiful. In fact, I think that the inclusions make this stone; a fingerprint of its creation. However, as with all of my stones, because I use a macro lens and the stones are magnified beyond their actual size, they always appear far more included in photographs than in reality.

Most blue and green tourmalines derive their colour from traces of iron, and they are sometimes known by the trade names of indicolite for blue and verdelite for green. Less common than pink stones, they are according more expensive and sought-after. This is a strongly saturated stone with open colour, and at 15.1mm round and 14 carats in weight, it is a substantial rock. It’s going to make a fantastic ring or centrepiece for a pendant, something like this one, below. I found it on 1st dibs, and it’s not credited to any known designer, but I love how they have called it a ‘dragon’s eye’, because that’s exactly what it looks like. I also hope it shows just how fantastically beautiful and effective a large, included stone can look. The stone in this piece is a whopping 39.5 carats and both more included and less saturated than my stone but it’s nonetheless an amazing piece.

Be inspired! And do it fast before temptation gets the better of me and I filter the stone into my personal collection! To view this fabulous stone, click here. It’s in my Hong Kong shop, but it ships internationally.

That thing you do…

White topaz 8mm rose cut round cabochons, $10 per stone

That thing you do when you look at a big pile of a particular stone and wonder why no-one has bought any for a while and when you check it’s because you haven’t had it up for sale. For months! And it’s one of those stones that people generally want in a fairly steady way. Well, just FYI, I do have it; 8mm rose cut round white topaz. $10 per stone, come and get it here. A real work-horse of a stone; white topaz does not have fire, but it has brilliance and lustre – in fact topaz takes such a good polish that can feel slippery to the touch. It’s a great option for a white stone, and good value for money too.
