by frackas » Aug 25, 2019 Hi everyone. I'm new to the forum and just getting into diamonds - a total beginner ! I'm trying to find a nice diamond pendant for my girlfriend, and found this one, which I liked a lot: https://www.kataoka-jewelry.com/en/categories/en-necklaces/diamond-solitaire-necklace-en/ I've never seen anything quite like it, there is a hole drilled through diamond, which is a 0.3 carat Sl1, F, very good cut. My question to you is wether a hole through the diamond like this affects the clarity and the brilliance in any way? And is the given diamond rating reflective of the drilled hole or not? I thought the pendant looked really nice and elegant, but I'm very happy to hear any concerns regarding buying a stone which has undergone this treatment. Thanks for a great forum!
