Old Navajo Sterling Silver Long Ring Pale Blue Turquoise Size 8

Old Navajo wrought sterling silver long ring. It has a hand cut scalloped bezel that is decorated with lumpy hand wrought raindrops. The stone is pale blue with almost black matrix. May be Carlin Mine, but is lighter blue than typical. The stone has what looks like a crack that is part of the matrix and does not compromise the integrity of the stone. It was not filled with resin as it would’ve be today. I have a side view of where it starts and you can see that it is part of the matrix. Stamped sterling in the old block letter style. Hammered and cold chisel split shank Size 8 Weight: 5 grams. No Navajo mark, too early.
