Platinum Marquise diamond ring ?

This item is a Platinum ring with a set Marguise diamond that is .6 carat. This item is unique in the way that the marquise diamond goes across the finger and not along the finger like most if you look at them. The clarity is VS1 on the diamond. It is 2 years old and it has a street value / insurance value of 3500. I am willing to listen to offers for this item and can supply pics if they are required. It comes boxed in its original box with authentification certificate and insurance certificate. All messages are welcome regarding the item.
