In 1991, a search for the Capitol Cornerstone was conducted including use of a metal detector to locate the engraved plate—it was not found.

From the National Park Service

Washington began his life as a Freemason in 1752 at the age of twenty when he was admitted into a small Freemason Lodge in Fredericksburg, Virginia. For the rest of his military and political career, Washington was an active member of Freemason social circles and established Alexandria’s Freemason Lodge No. 22 in 1788. Upon Washington’s death, Lodge No. 22 was granted many of Washington’s personal belongings, artifacts referred to as Washingtonia, including those related to his term as the Lodge’s first Grand Master.
