HOW TO CHOOSE

Because Sandawana emeralds are used several at a time in jewelry, and seldom singly, it is important to choose stones with well-matched color. Color matching is a job for an experienced professional, and it is important that stones in a piece are matched for cut as well as for beauty grade and tone. Based on these various requirements, one can see that jewelry containing Sandawana emeralds of gem and jewelry quality can generally be acquired only through reputable merchants of high standing.

The value of a 0.08-carats-size Sandawana emerald of jewelry quality is approximately US $160 for the stone alone (2004).
