Dalnu thinks the purple gem, an amethyst, well cut and large, should be worth about 15 gold. The opaque oval is a bloodstone and worth about 2 gold. The red sphere is a carnelian that should be worth about 7 gold. The glowing stone looks to be fluorite, and she would put its value at a few silver, except for the glowing.

(While RAW detect magic wouldn’t tell you what is magic, there are simple ways to do this that could be done with time. So, she wouldn't know now, but for latter.) The claws, glowing crystal, and all three large flat stones are magic. The other three gemstones are not.
