Presolar grains are tiny crystalline grains found in meteorites, such as the meteorite that created Meteor Crater in the desert of Arizona. These grains are assumed
to be older than the solar system. Scientist's calculations have shown that many of the presolar grains were
made by stars at or near the end of their lives. In particular, catastrophic
events such as supernova explosions and the dust from certain
red-giant stars, during their death throes, seem to have been major contributors
to the creation of presolar grains. system.

Micron sized silicon carbide grains were trapped in meteorites that were forming as our solar system was being shaped. The discovery of these refractory grains
has opened up a new branch of science and has also made a serious contribution to the world of precious gems and exquisite jewelry.
(Our Solar System)
Moissanite can be considered a presolar grain and, thanks to the scientists at Charles & Colvard, we can now own a Moissanite jewel that is identical, in every way, to the Moissanite stardust that was created so long ago.
