A chocolate diamond is a brown diamond, one of various types of colored diamonds. Other decorated diamonds, also called fancy diamonds, include pink, yellow, blue, green, purple, black, red and orange. Although colored diamonds were once considered undesirable, chocolate diamonds became more popular and are worn by those looking for an alternative to conventional white diamonds.

Most chocolate diamonds arrive from diamond mines in Australia. The natural happening brown color is thought to be created by the earth's pressure on the diamonds deep in the earth. The shades of a chocolate diamond vary, but the color is moderately dark. The Gemology Institute of America (GIA) rates the color strength of colored diamonds based on a scale from one to nine. Colored diamonds have the same hardness and other properties of white diamonds; only the color is dissimilar.

Several pieces of chocolate diamond jewelry feature white diamonds as well. The contrast between light and dark sparkling gems can look very gorgeous.

Attributing precious and semi-precious stones and to a set of twelve objects can be traced back to the traditional breastplate used by Moses' brother, a Jewish High Priest named Aaron. As described in Exodus 28, verses 15-30, the breastplate was decorated with 12 stones, one for each tribe of Israel. Twelve precious stones were also assigned to each of the Apostles in the New Testament.

By the middle Ages, sets of stones were matched up with the angels and archangels of the Bible and the symbols of the zodiac. In 18th century Poland, single stone amulets for every month of the year were made to be worn as a folk remedy for diseases.

The existing assignation of stones to months was established by the American National Association of Jewelers in 1912. Today, birthstones are worn for good luck and to improve the positive properties associated with each gem.
