REAL Native American Jewelry~

Will be visiting Santa Fe in November with my sisters. We're taking the 'girls trip' we were supposed to take with my Mother, but she passed before we could all go together. We're now doing it as a memorial to our Mother that LOVED all things Southwest from the jewelry to the decor. She had a wonderful collection of NA jewelry and we all inherited her taste in bijoux! I'm starting to get my shopping destinations in line, any suggestions for good places to buy NA jewelry in Santa Fe? I'm an avid auction goer and thrifter so was hoping to hit an auction or find a good rummage/thrift store. I did find "Real Deal Collection" for luxury items, has anyone visited this shop? Any suggestions I should put on the list or must see? TIA!
