In a similar way the Christian name of either of the betrothed may be indicated, as, for instance: S apphire O pal P eridot H yalite I olite A methyst 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.”[391] An attempt is being made in Germany to introduce the use of wedding-rings with moderate ornamentation and appropriate mottoes patterned on those of former times, in place of the severely plain gold hoop that has for a long time been decreed to be the only proper form of wedding-ring. If the tendency to over-ornamentation is kept strictly within bounds and if the mottoes are well chosen, there is some reason to think that the innovation, or rather revival, may meet with some success, as it will afford scope for individuality of taste to assert itself, and for the expression of sentiment in a way that has not been possible under present conditions. A wedding ring of iron and gold artistically combined has gained some favor of late, as symbolizing the union of strength and beauty, of the more solid with the more brilliant qualities. The uncompromising plainness of the plain gold ring, which represented a reaction to primitive forms from the over-ornamentation of the Rococo period, will probably give place to certain simple and chaste designs which can be made to symbolize some of the thoughts and sentiments connected with the marriage ceremony. But the unstable, oxidizing quality of the iron will not recommend this metal for durability.
