4 Carat Manufactured Diamond

4-carat lab diamond in beautiful condition. I paid a GIA-certified gemologist to examine the gem, and he confirmed what the documentation states. This is NOT a CZ. It is an early lab diamond. It has the same density has a diamond with slightly lower scratchability (similar to a sapphire or a ruby). The gemologist also confirmed it was 4 carats. See pictures for details.
