First of all your bracelets are breathtaking. I am an elder in the Sault Ste. Marie Chippewa indians. In my tribe blood quantity is not required,it is how long your family member(s) have been on the original census rolls. Mine dates to 1870. I am passionate about turquoise jewelry and it does not hurt that that is also my birthstone. I do not have a big collection but everything I own is authentic. Now one of my great joys is my husband and I helping to support Navaho elders.
