I asked my SA not too long ago about the price of the classic pearls (w/graduated sizes and the CC logo with pearls on it- part of the permanent collection) I was quoted $725 I believe.
$795 - I just purchased them during Saks Triple Points. I hit the whatever mark and got 18% back in gift cards so I thought it justified the huge price for costume jewelry.
Chanel seems to raise prices constantly, once they sell through one stock and send in new stock, it's higher pricing. I didn't want to wait and risk them running out and paying more. The pearls seem very nice.
