I really do like the fact how gems were placed on every characters in Steven Universe.
Both Pearl and Peridot have gems located on their forehead, signaling of their intelligence. I also liked that it’s located more on frontal lobe area, which is a function of a brain of thinking, planning, and decisions.
Amethyst’s gem is located on her chest area, maybe her heart, stating that even though she’s a bit rough around the edges, she has big heart. Heart is also symbolism for strengthening relationships.
Lapis gem is on her back, giving her an ability to have wings. I also liked that it’s shaped as an teardrop, a symbolism of her grief of being betrayed by gems. I still haven’t figured out what the significance of having her gem on her back is.
I have no idea why Jasper’s gem is a nose, but I liked it and it reminded me of someone having a huge ego…-shrug-
Garnet’s gems are on both of her hands (Sapphire and Ruby), because Garnet is a fusion, both her and her gems represents two opposites balancing each other, which is pretty obvious. I looked on line to see that hands are symbolized as justice, choice, balance and contrast.
Both Steven and Rose Quartz’s gem are located on the stomach, which is a symbolism of health, fertility, and good luck.
