I believe them to be trade names for garnets being mined and/or
traded in India. Google for the names alone and you’ll end up in
India. The Orissa is Almandine garnet if I understand correct.
The garnet group consists of 6 main members divided into two groups:
1: pyralspite (pyrope-almandine-spessartine)
2: ugrandite (uvarovite-grossular-andradite)
These are isomorphous groups, meaning that some of the endmembers
can be part of the structure in one crystal. For instance
pyrope-almandine is an isomorphous serie and somewhere in between
Other series are pyrope-spessartine, spessartine-almandine,
pyrope-grossular and grossular-andradite.
In those series you can fine intermediates with names as melanite,
malaia, tsavorite, hessonite, mali, topazolite, demantoid,
mandarine, hollandine, kashmarine, maralambo and color-change.
Those are the names recognized I believe. The rest are trade names.
We did a few chats on them a while back, you can read the logs at
