Question about the HCA

[Pupz]

How does the HCA apply to vintage or European cut rounds? We're looking for an engagement diamond, and considering all the options, but not quite sure how to evaluate cut grade for an older stone. Thanks!

OP - I had previously bookmarked this thread about the HCA and OECs... I think it answers your question https://www.pricescope.com/communit...-for-an-oec-if-you-have-all-the-specs.113736/
