I’m a little confused, what HCA score should we look for in a diamond 2.5ct or bigger?
We need the proportions but I can tell you if you look at that diamond from less than 1 foot / 30cm it will appear to be a bit dark because you are where the lights will be coming from.
It should be brilliant (but with a little less fire) - more a diamond I would use as a pendant than a ring. But a way better than average performer.
But as above - if you want to look at it from 6 inches you will be disapointed.
