瑠璃（吠璃瑠也亦云毗瑠璃叉言毗頭梨從山為名謂遠山寶遠山即須彌山也此寶青色一切寶皆不可壞亦非煙焰所能鎔鑄唯鬼神有通力者能破之為物或云是金翅鳥卵㲉鬼神破之此寶以賣與人間也）。

瑠璃 (beryl (vaiḍūrya): that is, vaiḍūrya; also written vaiḍūrya (毗瑠璃) or vaiḍūrya (毗頭梨). It is named after a mountain, meaning a gem from a distant mountain, the distant mountain being Mount Sumeru. This gem is blue in colour. All gems are indestructible and cannot be melted or cast by smoke and flame; only ghosts and spirits with supernatural powers can fashion it into objects. Alternatively, it is said to be the eggshell of the garuḍa, which ghosts and spirits break open to sell this gem to the human realm).
