Bound character, used in 玲珑 (línglóng), which means dainty and exquisite for objects, and clever and socially deft for people, as in 八面玲珑 (bāmiànlínglóng, smooth and tactful with everyone).
龙 (lóng, dragon) gives the exact sound. Historically the ritual jade this character named was carved with a dragon pattern, so the link is also faintly meaningful.
