I read about these Chrystal shards you can find way out in Sanguineous Rim. Well I think I found some of those a bit closer to the bubble.
It's on Hip 34208 2A, a small moon orbiting a gas giant. I haven't visited the sites out in Sanguineous so I can't say for sure that this is the exact same thing. There were Chrystal shards and formations of various sorts though and I got a few raw materials of different kinds. All in all there are 13 sites across the moon. Head for Meene and then Canopus, after that it's about 100 more ly. So not very close but closer... Happy hunting if you head out there.
