Are these South Sea Pearls"

[momsjewel]

I have these strung pearls without a clasp and are curious as to whether they are South Sea pearls because of the size. They measure 13 to 16 mm and have various tones to them, such as silver, gold, blue, pink, champagne. They were purchased in a lot of pearls online. Thanks to any for your help

Is 13-16mm the length of the pearls? Width around 9-12mm? They look like big freshwater pearls.

Yes, the 13-16 mm size is relating to some being smaller in length. I guess I was thinking South Sea because they are more satin like in appearance. Thank you for your response.

These are Chinese cultured freshwater pearls.

No doubt about it, they are cultured freshwater pearls from China.
Those are natural colors.

Some of the really long pearls makes it very clear. FW can be satiny too. It depends on the quality. It's not easy to find FW with sharp luster.
