ABSTRACT
Methods for the hydrothermal synthesis of four
new coloured varieties of quartz have been developed. Two of
these varieties are very rare in nature. They are a bi-coloured
amethyst-citrine (ametrine) and a phosphorous-bearing
low-temperature pink quartz. The other two varieties have no
natural counter parts. They are a pink-violet Ni-bearing quartz,
and a Cu-bearing quartz which resembles aventurine. The principal
conditions for producing these varieties of quartz single
crystals are described.
