Lander blue? Apache? Verascite? Chinese?

There is a small crack that is not visible to naked eye there, but does not bother me. I have seen lander with the popping large blue in the matrix and the tighter ones which led me to buy this piece so I am taking th partial refund of $1250 and keeping it, afterall turquoise is only in the eye of the beholder. I have no plans to resell.
