HOW TO CHOOSE

Because most tsavorites tend to be small compared to other colored stones, highly brilliant gem-quality stones are recommended. The optimum tone level will vary depending on the gemstone's size, as well as the style of jewelry and the stone setting method. A tone level of 3 with a beauty grade of S or A is also recommended for use in jewelry. Tone level 7 is most appreciated by gemstone collectors who enjoy loose stones, and is probably best avoided in jewelry. At that tone level, a stone will have a rich beauty under strong lighting, but appear black under weak light.

The value of a one-carat-size tsavorite of jewelry quality is approximately US $ 1,000 for the stone alone.
