Suddenly, out of nowhere, DIAMONDS. Well a freelance job I'm trying to get wants some realistic diamonds and i heard that cg diamonds can be pretty tricky so i decided to do a quick render. And yes they are pretty annoying to deal with since you're working with transparent objects that pick reflections up from super random angles. It's all about the HDRI and the right things to reflect I'm noticing. This is still a WIP of course. I might post the final here if i decide to finish it.
