Details
Lepidolite is Lithium in Feldspar.
This piece is covered in slivery, flower shaped, feldspar crystal formations.
It is intensely purple when polished.
If you plan on cabbing it, you could choose to polish it or leave it mat.
Either way (or both!) makes for a stunning cabochon.
This is NOT a good material for an unskilled lapidarist.
Due to the mixed nature of its composition, undercutting is likely.
Measurements are approximate:
6 x 2.5 x .25 inches (most useable area)
7 x 3 x .25 at the widest points
Mohs 5.5-6
