Bobby Etsitty squash blossom

Someone posted this necklace onto the r/nativeamericanjewelry subreddit looking for opinions.

The hallmark is attributed to Bobby “Slow Hand” Etsitty, but the only mentions I can find of him are for other sale listings.

The owner of the piece says it weighs 180g, that it isn’t magnetic, and they believe the stones are genuine. They say they’ve been told by experts that it’s genuine Kingman turquoise.

Thoughts?
