Calle de Berilo

Beryl is a mineral, colorless when pure, that turns green, blue, yellow or pink depending on the impurities running through it. Some of the most coveted stones come from this family: green beryl is the emerald and blue beryl the aquamarine. It hardly sounds like much on its own, yet its offspring fill jewelry cases. From its Greek name for a sea-green stone came, by a medieval detour, the German word Brille, eyeglasses, because the first lenses were cut from beryl. In this corner of Delicias, Berilo is a short street, barely thirty meters long, that shares with its neighbors a taste for mineral names.
