Precious (gemstone)
Traditionally, the four precious gemstones are diamond, ruby, sapphire and emerald. But other gems have also been labelled precious at times, including opal and amethyst. Today, the distinction between precious and semi-precious gems has been rejected by some gem trade associations. See also Semi-Precious gemstones.
