Here we have my favorite cut of Diamond in a classic Estate Platinum setting by a famous jewelry Designer Jeff Cooper. The Diamond is very white at F-G and free of inclusions but with some feathering, so SI2.
The ring is size 5.25 and weighs 4.3 grams which attests to the authenticity of the Platinum. A wonderful piece for a proposal.
Could you imagine being able to purchase such a quality ring in a regular Jewelry store? Not in this reasonable price band.
