Hessonite Garnet Garnet hessonite

The hessonite garnets maybe confused with the spessartite variety as they can both have similar colour.  In general, hessonite does not seem to reach the same high prices that spessartite does.  Hessonite has a diagnostic ‘roiled’ appearance similar to that seen when mixing whiskey and water that makes visual separation from spessartite easier. It also can give the stone a slightly resinous to sleepy appearance. Hessonite tends to range in colour from a light yellowish-orange to brownish-orange. Major mining locations include Sri Lanka and India, while other minor localities include; Canada, Mexico, Brazil, Tanzania and Madagascar.
