摘要： An artificial ornamental stone of cabochon shape comprising a transparent light or yellowish brown matrix in which are embedded parallel to the base of the stone transversely orientated parallel fibers with greenish yellow transparent cores having a selected index of refraction clad in transparent sheaths which may be defined by the matrix and have an index of refraction less than the cores. In producing the base material for the stone, the fibers may be clad in one or more sheaths and embedded in the lower melting point matrix or the fibers may be unclad or partially clad and mixed with lower melting point and lower refractive index fibers and the assembly fused into an integral mass. The stone may be covered with a thin colorless, transparent, hard protective coating.
