Hello, complete newbie here but I have fallen in love with the first thing I saw on this forum-- Baby Nurse's graduated white Edison necklace. Here is my question- I see large freshwater pearls on many site that are the same (wish) size as the one in Baby Nurses's necklace (9.2-12.2 mm) but they are not called "Edison". So my question is is Edison the same as "really big freshwater pearl". And any ideas on where to shop other than Pearl Paradise (they are currently teaching for me in HK) Thank you so much!
