[1] It was one of more than a dozen rare gems stolen in a heist from the American Museum of Natural History in 1964 and remains missing to this day.

[2]The stone was originally discovered by workers hired by Samuel Wood of Eagle, Wisconsin to dig a well on the hill where the current water tower stands.

After several years of fruitless digging, he spread inferior gems in the area to attract investors for his Eagle Diamond-Mining Company.

When Boynton refused her offer, Wood sued unsuccessfully to have it returned to her in a case that was ultimately decided by the Wisconsin Supreme Court.
