Barrera necklace

This was my moms. I have researched it to death and haven’t found this exact one. But this necklace is full of gray stones so I researched them. They could be: Hematite, Smokey Quartz, labradorite, Rhodite,?quartz, and a few more. It is gorgeous. 3 strand with matching earrings with crystals and a huge gray stone drop. The necklace has pearls black and silver. Spectacular
