I posted a comment yesterday with my calculations of the Stone's apparent size versus the Moon. My Dad pointed out that I neglected to subtract the Earth's radius (6,371 km) from the Moon's distance to a surface viewer, which makes it about .52ﾺ in angular size. And I assumed you meant the Stone, when inserted into Earth orbit by the Hexamon, was orbiting at 10,000 km altitude, not from Earth's center.
But at 1.65ﾺ angular size (for the long dimension), the Stone would be an impressive sight in the sky!

It would indeed!
