The International Gem Society (IGS) has a list of businesses offering gemstone appraisal services.

Coral values are based on hue, saturation, size, cut, and polish.

Top values for calcareous coral go to red, pink, and orange pieces. Other colors are graded separately. Highest values for conchiolin coral go to black, then brown. Gold color has additional value, especially if it shows a sheen. When polished, the color may shimmer through a transparent layer.

Coral growths come in many shapes. The coral commonly used to make gems is branched and treelike. The largest sections of a coral’s trunk are used for carvings, which can be quite valuable. The determining value factors are the size and color of the piece as well as the skill of the artist.

Most coral is cut into cabochons or made into a variety of shapes for use in necklaces as beads.
