This is an elegant platinum ring featuring a beautiful cabochon-cut Paraiba tourmaline. This lovely ring showcases a rare Paraiba tourmaline in an unusual cabochon cut. The Paraiba is surrounded by diamonds, and the arms of the ring are also designed. I bought this because I love Paraiba and the cabochon cut is rare, but the lovely atmosphere doesn't suit me, so I'm letting it go. While Paraibas with more transparency are considered more valuable, I think this cut and design actually match the milky appearance well. As stated in the appraisal, the color is a blue without green. The size is also 0.28ct, which is large for a single Paraiba stone. I purchased this at an authorized Estella store. I will send it in the ring case shown in the photos, along with the appraisal certificate.
