Big Square Turquoise and Unusual Silverwork on this Vintage Native Cuff Old Pawn

Love the unusual symmetrical design of the silverwork surrounding the beautiful big blue hunk of turquoise. Look at that great matrix.
The artist used coils of ropework and 4 spirals to make a perfect frame for the stone. Such an unusual piece, likely Navajo and likely one of a kind.
Nice quality split band with ropework and an applied silver leaf on each side
Tested silver.
The bracelet measures 5" inside with a 1" gap, weighs 44 grams. C 1970s
