Doctor Gulliver holding a star Sapphire[1]

A sapphire was a type of gemstone. One of the most valuable types of sapphires was the star sapphire.

It was believed Mr. Vanderbulge owned the world's most valuable star sapphire, which was called the Vanderbulge Star Sapphire. Doctor Hiram Gulliver used the sapphire to power his invention he made to broadcast his miniaturizing ray over television and radio, in attempt to shrink the world's population down to two inches tall.[2]
