Hi, Zelimir, List,
The easiest, though not conclusive, test would be
to have a jeweler or gem collector measure the index
of refraction of the suspected Moldavite. The index
of refraction for Moldavites is 1.46 to 1.54; for
man-made glasses, it's 1.52 to 1.55. If every Moldavite
in a selection
Scientists say the object currently has a 1-in-75 chance of colliding
with the planet, but that probability is expected to go down over the
next month as more observations are made.
Let me guess... it has a 74 in 75 probability to go down and 1 in 75
chance to go up?
I'm always amused over

The fake moldavite is made from soda-lime glass and
a simple refractive index test is all that is required
to test it.

Hi Göran:
It is all in the timing. If I remember correctly, when orbits are
calculated, the greatest uncertainty is in the time of perihelion passage
(where it is in its orbit). So, while they know the inclination of the
orbit (where it will be when it crosses the orbit of Mars), the greatest

It may be that the seller of the material was unaware that the material
