I ordered the 1 carat size because there were several reviews stating it was one carat per earring. There were also several reviews stating that same about the 2 carat size. The 1 carat is actually 1/2 carat per earring. I'm not sure what is going on with the sizing. Ordering the 2 carat earrings. Will see how accurate the carat size is on these. Gave it 3 stars because they are beautiful & the posts are fine as well. There was some discrepancy on how the post held up. Will update when the new earrings arrive.
