{"title":"變色藍寶石（附GIA報告）","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.
