Eagle Diamond

The Eagle Diamond was discovered in Eagle, Wisconsin in 1876 by a man named Charles Woods while he was digging a well. The land in which he was digging was not his own, it belonged to Thomas Deveraux, and Charles and his wife Clarissa were renters. Woods did not think the stone was very valuable, and believed it to be a topaz, because the color of the 16.25 carat (3.25 g) stone was a "warm sunny color". Some years later, when the Woods family fell on hard times, Clarissa sold the stone for $1.00 to a Samuel B. Boynton of Milwaukee. Sometime after the sale, Boynton took the stone to Chicago for appraisal where it was revealed to be a diamond, and worth at least $US 700.

Boynton sold the diamond to Tiffany’s in New York City for US$ 850. It remained at Tiffany’s until World War I. J.P. Morgan bought the diamond, and presented it as a gift to the American Museum of Natural History, in New York City. It was placed in the J.P. Morgan exhibit along with the Star Sapphire of India and the de Long Ruby until it was stolen on October 29, 1964 by Murph the Surf.

At that time of the stone’s discovery, it was one of the largest ever recovered in the continental United States. It has been hypothesized that the Eagle Diamond was probably cut into smaller stones and no longer exists.
