Tektite. Go with "t"

A natural siliceous glass of meteoritic origin found as loose, pitted, rounded fragments in various parts of the world. They have been considered of great mystical importance in many cultures for millennia. In Sanskrit they were known as "agni mani," which translates roughly to "fire pearl." The only type that seems to be of current gemological significance are Moldavites.
