Yes, diamond core bits are available for taking scientific samples for analysis.  I have used them with a standard power drill and water on meteorites.
Bore in, break off the core.  Cut off the fusion crusted end.  Fill the hole and cover it with the fusion crusted end.
You can then easily texture the filler and paint it to make the sampling less obvious.

I have done this in conserving totem poles to hide the bolt holes.  It's quite effective.

Conservators usually don't want such repairs to be invisible.  They want them to be obvious to a careful eye but not so obvious as to detract from the aesthetics of the piece.

Cheers,
Nick

It should be possible to take at least a core sample of the stone, leaving a fusion
crusted "plug" to cover the hole.  In this way, the stone can be studied by
scientists without detracting from its aesthetics.  Even if it's just an ordinary
chondrite, the fact that it is a documented fresh fall is rare, and therefore
scientifically important.  Short-lived isotopes may provide information about
cosmic lifetime, for example.

With the exception of providing a sample (as unobtrusively as possible) to
scientists, I quite agree that the stone deserves to stay intact.  --Rob
