[Since Jasper's grabbing the gem shards, Nira's going to bring the sword and set it on the podium, still with a cloth wrapped around the handle. She's also brought the drill bit from the workroom.]

I focused on studying the shards of the gem we found. Though not all of the shards were present-I think maybe about half of her gem left. Also, the break seems quite dissimilar to how quartz shatters-whatever Rose's gem was, it had basically perfect cleavage. I also tested its hardness with this drill bit, [She holds it up] which should be able to scratch quartz, and found that it was definitely on the harder side.

There was also blood splattered on the gem, and bloodstains on this sword as well. It seems the same sword was used to both draw blood and shatter the gem, since there is some damage to the blade.
