is the chuỗi hạt, chuỗi hạt cườm blair wears in 4x02 the same as the one Chuck gave her in 3x18?

I think the chuỗi hạt, chuỗi hạt cườm is different...

Nope it's not the same, but they do look similar from that screenshot bạn got from 4x02. The chuỗi hạt, chuỗi hạt cườm in 3x18 was from Cartier, but the one from 4x02 was from Harry Winston.
