Theoretically? Millions to billions of years. Practically? They will
last until the first time you forget to fill the dewar. Or until the
Sun explodes and in the rush to leave Earth your descendants forget to
pack it. Whichever comes first.
Seriously, as long as the crystals have actual
in theory I would say decades/eons.
in practice it probably depends on how much water/ice your liquid nitrogen
contains, multiple refillings of the liquid nitrogen might slowly deposit tiny
ice crystals on the crystals and slowly make diffraction worse...

Cryocrystals will last several months and more. Make sure that your LN2
is dry.
