Gold plastic base has "TM" initials printed along the top front and back of the ring base. Top of ring has clear plastic dome and within interior is an oblong black area representing the tiger eye. After exposure to light, the entire dome area glows brightly in the dark except for the dark slit. The resulting image represents a tiger's eye reflecting light. The black slit is extremely compact and not diffuse as on some examples. Ring glows brightly. Essentially Mint and one of the very best examples we've seen.
