Hi Patina,
I spent several hours on Saturday 5/10/25 closely examining and comparing more than a hundred good images of Bisbee jewelry, cabs and nuggets with each of the polished stones mounted on my newly acquired squash. As a trained scientist of many years who looks for small details I can conclude that all of the gem stones on my squash are indeed Bisbee turquoise with at least a 95% confidence limit.
There is no artisan mark or ID on the back of the Naja, however there was a crumbled price sticker reading $4000! A very high price in the 1970s. I checked back with the seller who confirmed that the price sticker was always there. Moreover she said her grandmother probably purchased it in the 1970s, not the 50s/60s period she originally guessed. I believe this forensic and comparative data support my conclusion.
Soon I will photograph each stone for your close examination. Thanks.

@Sleepingbeauty Hi ~ Thank you for the follow-up information. It sounds like you had a very productive day researching Bisbee turquoise. Yikes, $4000 was indeed a high asking price in the 1970s! I was hoping for a hallmark but, it’s not uncommon that the necklace isn’t hallmarked. Please don’t go to any trouble on my behalf by photographing each stone. I think your original photos are very clear and well done. And, I’m able to enlarge those photos on my cellphone.
