Natural Tourmaline 2.754ct Natural Diamond 0.83ct Ring arm width: 3mm Material: pt900 Ring size: 10.5 Quality: Loupe Clean (Diamonds are Eye Clean) With mini appraisal report I purchased this to accompany me during hospital visits and stays, but unfortunately, I realized that the blue color I wanted to see (the nuance of the tourmaline's color changes depending on the light source) rarely appears. So, it's very disappointing, but I'd like to pass it on to the next person before it gets too much handling... I've only tried it on, and it's been kept in its case. This is an extremely high-quality indigo tourmaline with a beautiful sparkle from the careful cut and a deep blue color. It looks more beautiful in natural light, appearing sapphire blue. ※ I will not be selling at a discount. ※ If you are concerned about the size, I will discount the resizing cost of 4000 yen, so please feel free to comment.
