When healed, Centi introduces herself as a “cabochan” rather than a “cut”.
This is a neat little reference to jewellery and real-life gemstones.
Cabochans are gems that have been polished but not faceted. A gem that is faceted is one that has been cut to give it a certain shape and to give it multiple sides (through which light shines).
So by that rationale…
…Lapis Lazuli here is a cabochan – versus Peridot being a “cut”. It’s very easy to see the difference in this picture!
