I'm extremely satisfied with the solitaire engagement I purchased. I was able to get a much larger diamond for the money which made her very happy!

My fiancé was across the country for a month and was coming back to our hometown to pick up me and our son. Mike made sure he got the engagement ring in less than a week, sized and all. The most beautiful ring you could ever imagine as well. Very thoughtful man with a great business!!! We will definitely be going to him for all future jewelry needs!
