Natural citrine is a pale yellow to orange,
and is much lighter than the heat-treated material, which
is dark orange-brown to reddish-brown. Most citrine on the
market today is actually heat-treated amethyst because natural
citrine is found only in large quartz deposits in small amounts.
All heat-treated material has a red tint, whereas the natural
specimens do not.
In many amethyst deposits, the amethyst has
been partially or fully changed to a darker brown citrine
due to naturally occurring high temperatures, thereby changing
the amethyst into natural citrine.
Citrine is a 7.0 on the Mohs scale.
