I purchased this ring to replace a 1.1 caret VSS Color G engagement ring, 6-prong setting in platinum that was stolen. For those skeptics who know what real jewelry looks like and who are suspicious whether this really looks genuine, here are my caveats:
1. Ring weight - don't let anyone hold these rings. They are very light-weight, and it is dead giveaway that they are fake.
2. Metal color - upon close inspection, the sterling silver is not as white as real platinum.
3. 6-prong setting - the profile view of the setting does not look genuine. There is a significant gap between the main diamond setting and the channel diamonds on the side.

Despite the caveats above, I would say that this ring looks acceptably genuine, especially if it is on your hand and the observer is friend-distance away (such as sitting across a table at a restaurant). The size of the diamond is right around 0.9-1.0 carat, which is not too big and does not lead a person to suspect it is a fake.
