White Buffalo / Howlite Rosette Petit Point Bracelet by Rosana Williams Navajo

Previously owned sterling silver rosette petit point bracelet by 

Rosana Williams, Navajo. Hallmarked on the back. It is set with spider web white turquoise. I think that this is howlite, but it might be white buffalo. 

It measures 1 3/8" wide. Interior measures 5 1/4" long plus the opening of 1 1/4" wide. Weight: 17.2 grams. Great condition.
