{"title":"变色蓝宝石（附GIA报告）","description":"\u003cp\u003eColor-change sapphire is one of nature's rarer tricks: a stone that shifts hue depending on the light source, typically reading blue-violet to purplish-grey under daylight or fluorescent light and shifting toward purple-red under incandescent light.
