Gem Glyph

Overview
The Gem Language is a phonetic/pictographic language that appears throughout Steven Universe. The majority of this language is shown in "Steven the Sword Fighter," on the columns of Pearl's Arena and in "Sworn to the Sword" on the columns of the Ancient Sky Arena. They also appear throughout the levels of "Attack the Light" on various scenery and through in-game dialogue.

Script
The developers of the show have not yet revealed a pattern to this language. It most likely is not a script of English, as it has more than 26 characters, and its letters seem to be simplified Chinese characters. Some of the characters that appear the same in Chinese are: 中 (meaning middle), 門 (meaning door), and 日(meaning day).
