A matrix is formed into a desired shape by pouring transparent liquid material into a mold. The material progressed from the liquid to the gelatinous state. Laser sculpting steps are performed when the material is still in a gelatinous condition to form small spots in the matrix. Because the material is non-solid gel when the laser beam applies its focused energy, there is no cracking or destruction. Intensity and duration of the laser pulse determine the size of the spots as does the timing in relation to the matrix material finally changing from gel to solid. Particular visual effects are produced at different degrees of solidity when sculpting. The liquid in the mold may be pressurized for removal of air bubbles after initial pouring of the matrix material and application of pressure after the laser sculpting controls the size of the spots in the finished product.
