Absolutely Perfect!

This was purchased as my engagement ring. We are both Irish Catholic and wanted something traditional and meaningful to both of us. This was the perfect twist on the claddagh ring and will match his claddagh ring wedding band. I love the Irish infinity symbol on the sides in place of where hands would go on a traditional claddagh ring. It is so unusual. That symbol is very meaningful to me and also shows that our love will last forever. This style is so unique. I googled for weeks to try to find something else I liked and there was nothing similar. Only traditional claddagh rings. Even in Ireland there was nothing like this. I was so happy that you have a showroom in New York that we could visit. I was so nervous about spending so much money online and not seeing it first. Melissa showed us the ring and helped us with diamond selection. She was wonderful. I love my ring so much. Thank you for such a great experience! ...Read More

The stone sparkles and the band is so shiny that it was actually difficult to take pictures or it cause the camera would incorrectly focus on the light that shines off it. My now Fiance adores the ring and said that it's perfect and just her style. ...Read More
