Gemstone by
 Color

Many people purchase gems by type - for example, they want to buy a sapphire, a tourmaline or an amethyst. But one thing we've learned in the colored gem business is that most customers are concerned above all with color, and are less concerned with gem variety, as long as the stone they buy is durable enough for their purpose.
Finding gems by color can often be difficult, since websites tend to organize their inventory around gem varieties rather than colors. So for those who want to know what their options are in particular colors, here is a list of gem types organized by color.
Since there are hundreds of color variations in colored gems, we have organized this list around "base" colors or color families. A red-orange gem would fall in the "orange" category and a blue-green stone would be in the "green" category.

Red

Red gemstones are actually quite rare, and mainly occur in ruby, spinel and garnet. There is some very fine red tourmaline (sometimes called rubellite), but it is not often found.
  • Ruby
  • Spinel
  • Garnet
  • Tourmaline

The most popular pink gemstones are tourmaline and spinel. Pink sapphire is lovely but rare. Rhodolite garnet tends to be purple-pink. For more about pink gemstones see our feature article on the topic.
