Abstract (en)
[origin: EP0250321A2] 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.
