Not sure who needs to hear this but..

Several years ago, a team of archaeologists excavating a megalithic tomb in Spain, uncovered an extraordinary dagger formed from rock crystal.

Experts say it's the most technically sophisticated ever to be uncovered in Prehistoric Iberia and would have taken enormous skill to carve.

This 5,000-year-old artifact is nearly 8.5 inches long and was found along with 10 arrowheads, four blades and a core for making weapons, all of which were rock crystal.
