海藍寶

古罗马老普林尼《自然史》（77年）载：「水手携海蓝宝可平怒涛，其色凝冻海水之魂。」大英博物馆藏罗马帝国时期海蓝宝护身符（馆藏号：1867,0507.35），刻尼普顿三叉戟纹，出土地中海沉船。
明《嘉靖常熟县志》记：「正德九年（1514年），渔人于扬子江获蓝石如鸽卵，夜悬网中则无蛟龙啮破，士人呼『水玉』。」南京博物院藏明代海蓝宝原石（编号：N19589），经拉曼光谱确认为巴西矿源。

Pliny the Elder's Natural History (77 AD) states: "Sailors carry aquamarine to calm storms, its color being the frozen soul of the sea." A Roman talisman carved with Neptune's trident (British Museum #1867,0507.35) was recovered from a Mediterranean shipwreck.
Jiajing Changshu County Annals (Ming Dynasty) documents: "In 1514, fishermen found a blue stone in the Yangtze River. When hung on nets, it prevented dragon bites. Locals called it 'Water Jade'." The Nanjing Museum specimen (N19589) is chemically traced to Brazilian mines.
