Always inspect the setting for loose stones prior to cleaning. Stones
that are insecurely set may fall out when cleaned by a steam cleaner.
Prior to cleaning, carefully touch the stone with a small probe (like
a toothpick); the stone should not shift or wiggle. If a stone falls
out as a result of being cleaned with a steam cleaner, please be
aware that the stone would have eventually fallen out anyway.
Most consider it better to have a stone fall out in a reasonably
controlled environment as opposed to at random while wearing it.
The following types of jewelry should only be cleaned by a
knowledgeable professional:
· Antique jewelry
· Enamel jewelry
· Paste jewelry (which is common with costume jewelry)
· Costume jewelry
· Jewelry containing stones that have been set with glue
