Can someone explain the .6 HCA on this ideal?

Found this through the diamond finder and it scored .6 on the HCA. Does that mean it’s not a good option for a ring?

No. Anything under 2 on the HCA is worth considering. For WF ACA or AGS 000 you don't need the HCA. The HCA is most useful for weeding through gia XXX stones.

Thank you! Makes sense.
