Gold plastic base has "TM" initials printed along the top front and reverse edges of the ring base. Ring top has clear plastic dome and interior shows oblong black area representing the tiger eye. With exposure to light the entire dome glows brightly in the dark except for this dark slit with the resulting image representing a tiger's eye reflecting light. The black slit is quite compact and not as diffuse as seen on many examples. Essentially Mint and glows like new.
