Seeing the uncut chunks of rose and blue colored stones on the table, Samuel reaches out and studies them by the fire for a few moments before setting them back down. Then turning his attention to the black stone necklace, he seems to spend a great deal of time looking at it, as if trying to make up his mind on something before speaking to you all. Finally his decisions made, he starts speaking speaking and while he might have entered at the end of the battle for the office, it seems he is trying his best to prove his worth to you all.
Uhm..before we split everything up, I think you all might want to know what these stones are. The red and blue stones are a type of quartz and since both are uncut, they aren't worth as much as they could be if they were properly shaped. Even with that limitation, the rose quartz will sell for a good price since it is pretty rare around here. The blue is more commonly found, but still worth several gold to the right seller.
Picking up the black necklace again, he feels the eyes of the room on him and warms up to his audience, their desire for wealth allowing him to grow more useful to them.
The necklace you took from the goblins is made of obsidian and has been shaped by a true master. Even in the Free City it would be worth a hundred gold easy, so we can only guess we could get twice that here in town.
