George Frederick Kunz,
Rings for the finger
(1917)
“ Although a diamond ring is the one most appropriate as an engagement ring, it has long been recognized that for a wedding ring nothing can replace the simple hoop of precious metal, which may, indeed, be rendered a trifle less plain by some very chaste and beautiful engraving. A reason for the preference given to the ring without setting is offered by Fuller in his “Holy State,” where he says: “Marriage with a diamond ring foreshadowed evil, because the interruption of the circle augured that the reciprocal regard of the spouse might not be perpetual.” ”
