This is a rare piece from the Chicago-based Hunter Gatherer (Hvnter Gvtherer) jeweler who created gorgeous handmade metalwork pieces with an occult vibe. This matte black Santorini Ring has a beautiful detail in where the two sides come together. It is too big for even my thumb so I have never worn it. It could also look cool on a necklace. It was sold to me as a 8.5 / 14mm ring, however I think it is larger. My ring sizer measures it closer to a 9. (I have two other Hvnter Gvtherer rings have I worn almost everyday for years, they are indestructible.)
