When I was buying my pig brooch, I was given the choice between gmop (old version) vs. Obsidian (new model). The obsidian just fell flat for me. There was no shimmer (at least that’s what I had imagined in my head given the picture of the grey with white flecks). For me, personally (don’t shoot me, please), I felt obsidian was a cheaper alternative to gmop. Gmop gave the pig dimension and the flashes of green/pink from the gmop was mesmerizing. If this HP is anything like the pig I saw, it’s just going to be a dark steel stone with a diamond in the middle, kind of boring IMHO.
