Genuine Turquoise Vintage 116 Beads 21" Drop Necklace With Tassel + Gem Stones

I 'inherited this piece of jewelry and know nothing about turquoise, or the origins of 'southwestern' style jewelry, I took this to my jeweler to make sure that this was authentic turquoise, which he confirmed. (I also believe this is vintage as he kindly indicated that this was 'out of style'. '70s?) I figured that anyone who loves turquoise or anyone who collects turquoise would know. There are a total of 115 stones approximately 6-8 mm and I measured the large stone at 2.75 inches (circumference) 92 of the beads (plus the large one) are genuine turquoise beads. 23 of the 115 stones are semi-precious stones/minerals (like Jasper) + amber or coral? (As he was not charging me for the appraisal, I did not ask him what each stone was - I just needed to confirm that they were genuine). I believe he said that the brown ones were (a specific type) of Jasper. The jeweler indicated that the large piece was 'reconstituted turquoise' meaning that it originally had small cracks which were filled in. *Barely visible in the last picture , you can see a small scratch like crack - (but it does not affect the structure of the stone.) The drop is approximately 16" -i around the neck are small silver beads for strength. (so well-made) *see next to last pic The 4.5" leather tassel is in great shape. So, it should hang down just about 21". * I am getting 3.4 oz total weight - although to me, it feels heavier.
