Aquamarine and pearl sterling silver station necklace

This necklace was part of an estate purchase and is in excellent pre owned condition showing a few signs of wear. Mostly perhaps due to the magnetic clasp being tied in a knot around it to most likely keep it securely closed.  Genuine beautiful big huge aquamarine teardrop stone hangs from the bottom of this beautiful necklace. The big aquamarine stone has some natural chatoyancy you can see in some photos. Smaller 8 mm aquamarine beads and white genuine cultured pearls stationed on a sterling chain with lobster clasps. Measures about 18 inches before the big teardrop aquamarine. Reasonable offers considered
