Dramatic studio-style key light from above, cyan rim light, warm inner glow, sharp crystal refractions, subtle volumetric haze, polished fantasy concept art, rich jewel tones, high micro-detail, clean silhouette, controlled depth of field, square format, no lettering, no symbols, no recognizable franchise elements.

中文提示词：

一枚神秘的悬浮宝石位于黑暗仪式厅中央，整体像经过设计的眼睛，却不呈现真实器官。水晶由蓝宝石、紫水晶与琥珀色切面组成，中心是一颗发光的珍珠状核心，仿佛注视着宇宙。细密魔法光环围绕晶体旋转，空气中漂浮着微小火花与半透明几何粒子。下方圆形石台接住彩色反光，背景沉入深靛蓝阴影。画面正面、完全对称，像一张珍贵遗物展示图。顶部戏剧性主光、青色轮廓光和温暖内光共同照亮锋利折射面，配合轻薄体积雾、丰富宝石色、高微细节与干净轮廓，画面无文字和符号。

说明：黑暗石室中央，一枚多彩晶体像宇宙之眼般静静悬浮。
