:Black Pearl:

Remember those Pearls I made some time ago? this is them now, feel old yet? This is basically how I imagined their fusion, Black Pearl.

Also, just an explanation about the gem on her chest: I have this headcanon that when two Gems with the same rock placement fuse, their rocks turn into a new one. The gem on her chest takes the shape of a natural pearl (I saw one lke that once, but they have varied shapes).
