When it comes to colored gemstones, color is king. Today, many customers prioritize color and are less concerned with the actual gemstone variety as long as the stone is durable enough for their purpose.

However, finding gems by color can often be very difficult especially since gemstone dealers tend to list availability by gem type or gem variety rather than gems by color. When most people think about a black gemstone not many types come to mind, but there are a number of other black gemstones available today.

There are several black gemstones that did not make this list, mostly due to rarity, or they may be black in other ways; such as, a multicolor stone that contains black or a bi-color stone that has parts that appear to be black. We felt that this guide should only list those gem types that can be found in black as their primary color. So, using our guide below, click on any of the gem types to learn and shop some of the world's most popular white gemstones available today:
