An apparatus visually duplicates the hue, tone, intensity and shape of a selected gemstone by combining predetermined intensities of red, green and blue light sources within a color mixing box. A single variable intensity light source and a monochromatic filter provide each of the three colors. Colored light from each light source is passed through a portion of a multi-segment diffusion lens prior to entering the color mixing box. The three separate colors are combined within the color mixing box and reflected from an image wheel which includes various geometric patterns. Light propagated from the color mixing box passes through a silhouette wheel to a crystal wheel which provides an appropriate gemstone shape. The light then passes through an image magnifier which controls the apparent size of the gemstone. Controls are provided to modify the shape, color and intensity of the duplicated gem displayed by the apparatus.

Apparatus for reproducing the color and intensity of a selected gemstone, comprising: a housing having a viewing port; a source of light of variable frequency within said housing; means for selectively changing the frequency of said light to obtain variations in the color of said light passing through said port; means for changing the intensity of said light passing through said port, whereby changes in the intensity of colored light exiting said viewing port may be controlled to conform with said selected gemstone; and imaging means optically coupled between said light source means and said viewing port for visually duplicating the structural appearance of the selected gemstone.
