Ruby (NPC) - 225gp for one unit, so 450000gp for 2000 units
Amber (NPC) - 150gp for one unit, so 300000gp for 2000 units
Citrine (NPC) - 150gp for one unit, so 300000gp for 2000 units
Star Sapphire (NPC) - 375gp for one unit, so 750000gp for 2000 units
Total for just the NPC is 1,800,000gp. (I've probably got the wrong idea but it was fun working it out lol)
Or is it just 2000gp worth of each gem? Thats alot easier lol.
