Sorry I misread.
Here his read me. It's in the v.m reads. it;s called VA_GemReplacerReadMe

Gem Replacer v1.0 by VagabondAngel
Just a little mesh replacer for Soulgems and Ingredient gems (diamond, emerald, and ruby). All the new meshes are 20% transparent and have coloured reflection maps to simulate sparkling gem facets.
Installation:
If you are reading this, the mod should be installed already from the self extractor. Otherwise you can extract the files manually and move them to your desired location.
There is no .esp (Plugin) file with this mod - it is just a mesh replacer. Once installed it will simply replace the applicable objects automatically.
Notes/Issues:
None that I am aware of. The models are low poly and the ref-maps are v.small so should not affect FPS on most machines.
Credits:
Original freeware gem meshes from
http://www.3dlapidary.com/Home.htm (edited and re-mapped by me)
Usage:
This is a playable mod and a resource. Feel free to retexture and re-distribute the meshes on the usual conditions:
1. You must rename the meshes/textures/icons to unique IDs
2. You must include my name as creator and my email:
chris@vagabondangel.com3. Send me a link to your project or a couple of screenshots at least

The packaged mod may also be uploaded to any Mod Site that hosts Morrowind mods, providing it is left in its current state as a self installer and the contents remain un-altered.
Enjoy

--------------------------------------------------
I just checked the path and it refers to a folder called VA, which is it's own folder in your texture folders.
I double checked and I can't get them to load. So just delete the three meshes and the game will return to the default meshes.
