![]() I find in my search for the treated things like those now are either a hydrothermal or irradiated material and I do know the hydrothermal is stable and the nuked stuff usually is not in the pastel colors. It was stable then as we used to set them in a window facing south for weeks along with gem minerals like kunzite, morganite, etc. I have heated the material myself many years ago when it was available but not any longer. It was a form of lighter amethyst (natural) that they found would heat not to orange or golden yellow but a mint to medium green. ![]() The vermarine or prasiolite or any other name it may go by green amethyst used to be from the Montezuma district of the gem rich Minas Gerais, Brazil. I thought that the traditional treatments of the stones above were seen as stable, and now I'm confused.Ĭorrect me if I am wrong as I have been once or twice ![]() I don't know anything about morganite and kyanite, but it they are particularly prone to fading, I won't buy any. The impression I had about aqua, blue topaz and smoky quartz is that the treatments accepted by the trade - heat and/or irradiation - were very stable. I read around the subject and I never heard any suggestion that the treatments of aqua aren't stable, and also I never heard that smoky quartz and blue topaz weren't stable, either. I believe my aqua to be unheated due to its blue-green color, but I also have a heated aqua pendant. I read quite a bit about aqua when I bought mine, and I never read about fading. In reading about this topic, I also read that morganite, kunzite, aquamarine, smoky quartz, and all kinds of irradiated stones can fade! Huh? I've always read that blue topaz (irradiated of course) is stable, and I've certainly never heard of aquamarine fading. Would wearing it around town on a sunny day at around 80 degrees fade it? I'm just confused over how much heat and sun is needed to cause this fading, and if you really have to expose it relentlessly for the fading to happen, or if casual summer wear can do it? Is fading a real threat, or is it something that "can" happen but in fact rarely does, unless you expose it heavily to the sun over a long period of time? I don't wear my jewelry to the beach or pool, and I don't take it on vacation. Kiki McDonough sells green amethyst pieces for around 1000-7000 American bucks (although my Kiki green amethyst earrings were nothing like that price) and if green amethyst faded, surely she'd be plagued by angry customers saying how their stones had changed color?ĭoes this fading happen only if someone wears the stone regularly in direct sunlight on a ninety-degree day? Or does it happen with weak sunlight all year round? I live somewhere with long, cold, snowy winters, and while it can get very hot briefly in the summer, I don't really wear my jewelry on a very hot day as I just don't want my nice stuff getting all sweaty. ![]() So imagine my consternation when I go to read a little more about green amethyst and I see that it fades in sunlight! I have researched green amethyst before and never come across this. It was incredibly inexpensive - so cheap that I won't mention the price because I fear you'll think badly of it when I show it in SMTB! But it's a large, green, sparkly stone, and I adore it. Last night I bought a really stunning large green amethyst ring set in silver. I have numerous pieces of green amethyst set in silver which were all very inexpensive, and one pair of green amethyst pear drop earrings set in 18kt gold from an expensive jeweler, Kiki McDonough. I love the beautiful seafoam green, which reminds me of the ocean, and I also think it's an incredibly tasteful shade. I'm not talking about rare natural prasiolite, but about purple amethyst that was heated to produce the light green stone commonly known as green amethyst. Hi, I know that green amethyst is prasiolite.
