Purchased at an antique shop in the UK during the bubble economy. The shop owner told me that it was an unprocessed old item and likely from Kashmir, as I was looking for a Kashmir sapphire at the time, so I bought it cheaply. After returning to Japan, an expert examined it and said the color was too pale, suggesting it was from Burma or Thailand, not Kashmir. I asked several other people afterwards, and they gave similar opinions. I considered sending it to Gübelin for appraisal, but at the time, Gübelin's origin appraisal was very expensive at 400,000 yen, so I gave up and kept it as is. The color is indeed light and pale, but I liked it because the cut was old and beautiful. It's a size 17, but because the back is thin and handmade, it fit me perfectly, even though I usually wear a size 19. Please examine the photos carefully and consult with me in the comments section.
