1911 Encyclopædia Britannica/Bezel
BEZEL (from an O. Fr. word, cf. Mod. Fr. biseau, basile, possibly connected with Lat. bis, twice), a sloping edge, as of a cutting tool, also known as basil. In jewelry, the term is used for the oblique sides or faces of a gem; the rim which secures the crystal of a watch in position or a jewel in its setting, and particularly the enlarged part of a ring on which the device is engraved (see Ring).
