(57) An ornamental article such as a pearl necklace has a plurality of gem objects each
having a spherical surface and a through hole extending substantially perpendicularly
to the spherical surface, a string threaded through the gem objects to interconnect
them, and a plurality of spacers of an elastomeric material interposed between adjacent
ones of the gem objects and having through holes through which the string extends.
The spherical surface of each of the adjacent gem objects has a radius of curvature
of r. The thicker central portion having a thickness of at most 0.4r, each spacer having a radius of at most 0.77r. The string may be nonstretchable and coated with synthetic resin or natural resin.
With this arrangement, the gem objects can easily be threaded on the string. The string
is prevented from being subjected to undue tension even when bent strongly, so that
the string and the gem objects are protected against damage in use or sale.
