    摘要: An imitation gem consisting of a semi shell of a transparent plastic material with concave inner and convex outer surfaces has light reflecting and light refracting facets formed on both its inner concave and outer convex surfaces. The open end of the semi shell is closed by a cover which is also provided with facets so as to further improve light reflection and refraction.
