    Coloured Gems

    Gems 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. Since color is indeed the most important factor for most people when it comes to buying loose gemstones, it only makes sense to start your search by shopping for gemstones by color.

    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. This means that a red-orange gem can fall into the "orange" or "red" category and a blue-green stone would be in the "green" or "blue" category.

     

    Red Gems

    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.

    Multicolor Gems

    In the category of multicolor gemstones we list those gems which display multiple colors in a single stone. Some of these gems, such as tourmaline, fluorite and ametrine, have zones of different colors. Others, such as andalusite, are strongly pleochroic and display different colors from different angles.
