Sterling Silver and Petrified Wood bracelets - 1940's Native Made

Just finished this auction ... and have only 6 of these pieces available.  Quite the collection, though.  I love the old polished petrified wood look; like no other.  These are all very good sterling work  - heavy sterling from the "old style" Navajo work.  This from an auctioneer that I really trust.  His knowledge of old school Native jewelry is exceptional.  If he says "made in the 1940's" .. which he did on each of these (save the 2 he puts in as "vintage", I have no doubt.  

Each is unique; no more of these on the horizon.   I've seen similar before at $1000 plus!  You be the judge:
