Is Merilani Mint garnet the same as Tsavorite?
No, Merelani Mint garnet is not the same as Tsavorite. Both are green grossular garnets but the mint garnet does not have enough color saturation to be considered a tsavorite. They occur in the same geological environment but the Mint garnet is not imparted with enough chromium or vanadium to give it the saturation necessary to call it tsavorite. This is like green beryl vs emerald or the difference between pink sapphire and ruby.
