Vessonite garnet

any one have experience or knowledge on this variety of garnet ? It is not listed in the garnet section. Thanks

There is no variety of garnet known as “vessonite.” However, that might be a misspelling of “hessonite garnet,” a variety of grossular garnet. It seems that some vendors occasionally sell grossular garnets and/or vesuvianites (which is an idocrase, not a garnet) as “vessonite,” but this is not a generally accepted trade practice.
Here are some discussions on this topic:
