Instructions
Pressurize gem constituents in a rotating, gold-lined and airtight chamber at about 450 degrees C.
Suspend a natural yellow beryl seed using a platinum wire to initiate growth.
Add a solution of highly concentrated hydrochloric acid to prevent the chromophore (the part of a molecule that gives it its color) from precipitating.
Wait 40 to 60 days for large crystals of synthetic emerald to form. (Note that these crystals may continue to grow for months.)
