Hi Shawn,

I doubt it will change the value of Allende, but it is one of the
cooler new names for a discovery:

"The mineral is named after the composition "Ti" and the word "star,"
implying that this new refractory mineral is among the first solids
formed in the solar system."

And to top it off, Allende has traces of nanodiamonds from near by supernovas, making the fine-grain microscopic particles older then our solar system.

My question is how will this new mineral impact Allende meteorite in the science and meteorite communities and what significance will it have on future discoveries for new minerals?
