Look at this beautiful gem! She’s so pretty! I really like the colour scheme, the shades of blue and green go very well with her. I also got to say that I agree with their decision of her having only one eye because if there was another eyes it probably wouldn’t be as effective.

I also immediacy though of a name when I saw her, the name has nothing to do with gems but I still like it. Olie, short for Olivia.

I researched a bit and found a gemstone that I think in my opinion is her (I’m not an expert btw)

Chalcedony. Yes it’s a long name but I think the colours work really well.

Both pictures kind of look like the (jell?) that surround her, especially the first one.

The second picture looks like the colour of her eyes.

So yeah, this is just a guess, please tell me what you think her type of gem is, I haven’t done a lot of research though so…
