by thirdrock » Apr 8, 2019 I’m looking for a 9mm round stone to go in a setting I have. A gemologist has ordered some in for me to look at. So far, the photos on some of the stones do not look good to me. Also, the prices seem high for the quality. I haven’t seen them in person yet, but I thought I’d run in by here. Lotus garnet $2,650 Gray Spinel $2,650 Tourmaline $1,350 The garnet and spinel are around 3.25ct. I’m not sure about the tourmaline.
