Introduction of Synthetic ruby
In 1837 Gaudin made the first synthetic rubies by fusing potash alum at a high temperature
with a little chromium as a pigment. Other processes in which synthetic rubies can be
produced are through the Czochralski's Pulling process, flux process, and the hydrothermal
process. Most synthetic rubies originate from flame fusion, due to the low costs involved.
Synthetic rubies may have no imperfections visible to the naked eye but magnification may
reveal curves,striae and gas bubbles. The fewer the number and the less obvious the
imperfections, the more valuable the ruby is; unless there are no imperfections (i.e., a "perfect"
ruby), in which case it will be suspected of being artificial. Dopants are added to some
manufactured rubies so they can be identified as synthetic, but most need gemologicaltesting
to determine their origin.
Many ruby colors for you to choose.
