Well, way before PS I purchased a pair of diamond studs off an online auction platform. Good size, fabulous price (should have sensed something then) and they came with some sort of (probably faked) cert, stating they were VS2. Bad pictures, but I went for it anyways. What can I say... they were bad... very included - says me, advocate of „not perfect stones“. I took it as a lesson and kept them. Too tired to take the hassle to return them. And too embarrassed to try to sell them on. So what to do with them? Well, I started wearing them as hiking and skiing studs. The inclusions remind me of crystal and snow, so perfect for my beloved mountains. And so I came to peace with them. Have you ever made a jewellery purchase sin? And what did you do?
