I am not quite sure I know which knots you were refering to... But they are all from one of my friends so I assume they are from same source.

To Satine, thank you for your encouragement! I will try harder

To Elsa, thanks first. And were you asking if they were fresh water cultured pearls? I think so, yes. My friend is from Zhuji, Zhejiang Province, China. That city has huge FW pearl culture farms so I think those necklaces are FW cultured.
