|[C17: from French facette a little |
facet fac·et (fās'ĭt)
A small smooth area on a bone or other firm structure.
A worn spot on a tooth, produced by chewing or grinding.
flat, polished surface on a cut gemstone, usually with three or four sides. The widest part of a faceted stone is the girdle; the girdle lies on a plane that separates the crown, the stone's upper portion, from the pavilion, the stone's base. The large facet in the crown parallel to the girdle is the table; the very small one in the pavilion also parallel to the girdle is the culet. Certain stones, such as mogul cut diamonds (egg-shaped jewels faceted without regard for symmetry or brilliancy) or drop cut stones, have neither a girdle, a crown, nor a pavilion. In others, the crown and the pavilion are identical-e.g., in baguette cut stones.
