Any rare crystal
that is created through an artificial process. Synthetic gems
are usually made in "bombs
" which are either stainless steel
. They are made to withstand high temperature
s (2000+ C) and pressure
s over 100 atmosphere
s. The trick is controling the temperature and inclusions during the cooling process. Most synthetic gemstones display phosphoresence
after being exposed to UV light
, due to included nitrogen
(wich diffuses out during the thousands/millions of years during which natural gems are formed). Artificial gems also have boundaries
where it can be seen where the seed crystal
was and the new growth began.
The stuff gems are made of...
