Could anyone help me with the maker and the stone of this shadow box bracelet

This bracelet has typical Navajo stamping, but can anyone help me with the name of the artist and the stone? I believe this stone is a lapis lazuli, but I’m not sure. And I can’t find this maker’s mark, but it’s maked CP

Yes that looks like so-called denim lapis.

Felix Perry, Gaynell Perry and Martin Perry are Navajo shadow box artists whose cut-out looks like that. So I’m wondering if half of that signature is a “P.”
