All the gems you mentioned are purple, and the drawings are available at Haishan NPC. Need the reputation and friendship of seamounts.

Then sell it in the NPC above Que Island, which is from the hotel.

As for the exclusive drawings of jewelry (including the stone you said 12 was specially cut for yourself), you can find drawings to buy from every prestigious quartermaster in outland.

If there are color pictures, many of them fall from the world. If you practice jewelry, remember to brush the reputation of the Astral Consortium. There are many jewelry pictures.
