QVC Milky Aquamarine and Freshwater Pearl Sterling Silver Necklace

This Pre-owned QVC necklace has a substantial center pear shaped Milky Aquamarine pendant, smaller Aquamarine beads, and cultured Freshwater Pearls on a Sterling Silver chain. The top of the pendant is a domed cabochon and the back (see last pic) is flatter so it rests against you, & it's shown on dark and light backgrounds to show how the blue color looks. The 18" chain has a lobster claw clasp and it's marked 925. Does not come with the original box. This necklace seems to have sold before through more than one retailer and it is currently available from Amazon under the brand Belacqua, currently selling for $85.
