Initially purchased a size 10 which, for all other rings, fits perfectly.  I received a size 10 which was very tight.  I left negative feedback at first because I had trouble reaching the seller.  Subsequently, the seller contacted me via telephone and offered to send a larger size and waive shipping costs.

This, to me, indicates the seller stands by their product(s).  I'm waiting for the replacement and will update once received.

For now, I'm rating five stars for the ring's handsome looks and the seller's attempt to make the customer happy.  I will purchase from this seller again because of customer service.
