A diamond
should be soaked for 20 minutes
in solution of one cup of warm water and 1/4
cup of ammonia. Gently scrub it with a soft-
bristle toothbrush. This helps get into the
small areas between the diamond and the
setting.
Rinse with warm water, and lay on a tissue to
dry. If diamonds are set in platinum, this
method will also bring shine back to the setting.
Avoid contact with chlorinated pools or
household cleaning products containing chlorine
bleach because they might discolor the mounting.
