Statement Necklace - Black And White Pearls, Pink Hearts, Green Peridot

Unique statement necklace with Peacock color pearls (they look like Black Tahitian pearls), large natural white pearls, natural green peridot, pink heart crystals and clear teardrop crystals. There are also three leaf shaped stones in the center, not sure what kind. Silver color clasp has some tarnish due to age, could be sterling silver, but it is not stamped. 20" long. Black pearls look natural and may be real Black Tahitian. They are of baroque shape, some have visible birth marks, as pictured.
