Anyone have any idea what this gem could be? Real? Fake etc
Hi, I bought this ring from eBay 20 years ago, and it was sold as a "Colombian emerald", but as soon as I got it I knew it wasn't that, it was way too clean and I thought I'd been scammed, and in fairness I didn't pay much for it, so accepted that I brought it on myself. I've had it sitting in a junk drawer ever since as I thought it was glass. I put it on the other day and noticed that it changes colours depending on the light. Vivid green in sunlight, forest green under a shade tree, icy sky blue when it's cloudy and in dark rooms and electric light. And it falls down under a specific yellow lamo I have and goes a dull.oss colour. It sometimes has an ethereal glow in very low light (closed curtains darked room in the day) It has a K stamp, but I can't make out it is 10, 14 or 18 K. I thought the halo was cz, but some of them fluorece under UV light, some are milky, some are inert, the stone is inert under UV. Does anyone have any ideas what it could be? I'm trying to work out if I should bother getting it looked at, it's a very long trip to the nearest gemologist to me, so I want to try and get an idea of if would be worth doing. Any help would be appreciated.
