Ametrine is the trade name for bi-colour amethyst; part amethyst, part citrine – see what they did there! In many ways it’s the panda bear of the gemstone world; it only comes from one mine in Bolivia, and given that citrine is effectively amethyst that has been heated, what you are looking for are amethyst crystals which have been partly heated by processes in the earth and partly not. Then you want to find a nice clean crystal that will co-operate and give you an nice gem with a balance of both colours. In the past, the classic cut was a step-cut rectangle with an ideal proportion of 50/50 amethyst and citrine. These days, however, all kinds of arrangements are common. I’ve seen ones where the cut-off runs diagonally through the stone, and fancy cuts and concave cuts scatter the light and create all kinds of interesting colours and effects. I have for sale just a few of the classic rectangular step cuts, with good proportions and also a few concave cuts. Concave cutting is interesting as it involves cutting conical facets with 3 dimensions, so that each facet has depth as well as length and breadth. This means that more light is refracted and the stone appears more brilliant. In addition, the facets create a fascinating effect. To shop the range, click here.

Finally back in stock, I have 4mm tourmaline cabochons – as I’ve mentioned, the price of tourmaline seems to be finally stabilising and so I can with great excitement announce a price-drop on these! Now only $4.75 USD per cabochon. As usual I have plenty in pink and fewer in the blue-green shades. This is nice quality material, with just a few inclusions here and there, and great saturation and lustre. To shop all 4mm tourmaline, click here.
Finally I am re-stocking tourmaline! I’ve been low on all sizes for a really long time, and that has reflected the way in which tourmaline has skyrocketed in price over the past few years. It went from affordable to eye-watering in what felt like the twinkle of an eye as the markets went crazy for its astonishing colour range and vibrant tones. In particular the Chinese market went mad for the deep pinks and reds and this drove prices up sharply and fast. Now it finally seems to be slowing and my long hunt for nice, reasonably priced material is temporarily over! I have just restocked 6mm in all colours, and will be following up with 3mm and 4mm over the next few weeks. This is nice quality material, with a few inclusions, but full of lustre and shine. As always, I have relatively few of the blues, blue-greens and chrome greens, so if you are after these, you might want to get in early! Plenty of pinks and grass greens. Price per cabochon has held at $18 per stone, and you can browse the selection here.
I’m always excited when I have new tourmaline in stock. I think it must be my favourite stone, with its unparalleled variety of colours, from soft pastels to vibrant primaries.
Egyptian legend has it that the tourmaline, when travelling up from the centre of the earth, passed over a rainbow, and in so doing assumed all of its colours. Whether or not you believe that, the name tourmaline comes from the Singhalese ‘tura mali’, which translates to something like ‘stone with mixed colours’, referencing the spectrum of colours which this stone displays. Here I have just listed a veritable bouquet of rose cut freeform tourmalines. I have single colours, bi-colours and parti-colours, with quality ranging from included to nearly clean; soft pale pinks, to vibrant bubble-gum shades, sharp apple greens, neon yellows, and deep, dreamy blues. All of them are lovely; every stone with its own special character and each one unique. These would look fabulous on their own, or keeping each other company in spectacular fashion. As with all of my freeforms, these stones are rose cut on one side and tabled on the other, so can be set either way up, in a bezel, window or prong setting.
