AI overview
I don't have enough context to write an accurate overview of ruby. The provided context only shows an image caption about ruby-producing countries, but contains no information about what ruby is, its properties, uses, or significance. I cannot provide a 2-sentence overview without inventing facts, which you've asked me not to do.

红宝石，屬於寶石級剛玉，傳統上作為樞要寶石之一，被用於製作宗教儀式用品和皇室珠寶。红宝石主要成分是氧化铝（Al2O3），红色来自铬（Cr）。自然没有铬的宝石是蓝色的蓝宝石。 天然红宝石大多来自亚洲（缅甸、泰国和斯里兰卡）、非洲和澳大利亚，美国蒙大拿州和南卡羅莱納州也有部分生产。天然红宝石非常少见且珍贵，但是人造并非太难，所以工业用红宝石都是人造的。
