                                          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.
