Quartz is one of the most ubiquitous gemstones; whether amethyst, citrine, rose, smoky or lemon, it’s plentiful and reasonably priced and you’re not going to have to part with a limb to buy it. It comes in so many different colours, including the fascinating and beautiful rutilated varieties. I want to talk a bit about lemon quartz, as it’s one of the family of treated quartzes and is a bit of an unsung hero. It’s a stone that cuts and polishes nicely and you can have it in pretty large sizes due to the relatively low carat price. Whiskey quartz, lemon quartz; nice lustrous stones in good sizes. Lemon quartz is irradiated with cobalt 60 gamma rays at very low dose (the stones aren’t glowing!) and then heated. The other thing that people aren’t generally aware of is that comes in different intensities of colour – and I don’t just mean that bigger stones are more saturated; you can get it from pale to much more intense yellow-green. My supplier tells me that people use it as a substitute for peridot, but I don’t think it’s that dark. It is on the same fresh, citric yellow-green spectrum, however. I used to sell mine – which is darker than standard lemon quartz – as green-gold quartz, to differentiate it, but it was too much of a differentiation, as people didn’t know what I was talking about and after I got asked a few times if I stocked lemon quartz, just changed the title! But it does have good saturation and is more of a yellow-green than pale yellow; I think you need it with a bit of saturation otherwise it looks a bit wan. The colour is more like a chrysoberyl and I think it really comes into its own when it’s mixed with other gemstones. I love the combination with citrine, which you would think would be a clash; the warm gold and the cool lemon, but it works. I also absolutely love it with the ruby, and I never would have thought about pairing these two, but they look amazing. In fact, I think I do like this stone best when it’s warmed up with gold, or golden stones, as they just seem to make it glow.
