Buying off your gut isn''t necessarily a bad thing. It means you''re choosing what pleases your eye, and as long as you''re doing that, it''s a good thing.
If you care about the ''score'', though, I''m assuming you mean the HCA. The HCA generally regards diamonds scoring at 2 or below to be worthy of further consideration.
Keep a few things in mind when using the HCA:
1. A ''lower'' score isn''t a ''better'' score - think of it as pass/fail. 2 or under = pass.
2. Remember that HCA isn''t a selection/tool; it''s strictly meant as an elimination tool. It''s primary goal is to discard what''s likely chaff and leave you with what''s most likely ''wheat''.
