Garnets are complicated little buggers, chemically speaking.
Hessonite is a color variety of Grossular garnet and thus in the Ugrandite group. Spessartite is an end-member of the Pyralspite group.
The Gemology project page on garnets has lots of good information. But, in order to keep it simple, think of it this way: the difference between the two is that Hessonite has Calcium and Spessartite has Manganese.
thanks
to both
they look alike. both beautifull ,if they aren´t cab grades.
only with time i start to understund diferences. and most of them only can be seen by science instruments.
wow, n00b!! that's some intense color that nigerian spessartite is sportin'!! hessonite can be a beautiful stone as well, though, pedro. it's probably my fave in the garnet family.
