Huge freshwater pearl necklace

The pearl is perfect round and nearly flawless to the eye. The luster is superb and you can see my reflection so clearly !! It is more than 12mm in size, sitting in a sterling silver flower setting. Absolutely astonishing! The sterling silver chain is 19 inch long but any chain will fit to the pendant. There is a tiny cz missing if you look super close in the 2nd picture. I will ship with a velvet jewellery box. Thank you.
