Horchow carries a similar convex sunburst mirror. Here is a link http://www.horchow.com/p/Oversized-Sunburst-Mirror-Wall-Mirrors/cprod76660216/?ci_sku=cprod76660216sku&ci_gpa=pla&ci_kw={keyword}

Thank you.

ZGallerie carries a somewhat similar piece http://www.zgallerie.com/p-11011-phoenix-mirror.aspx

Home Depot carries a smaller version by Martha Stewart but it is only available in a brass finish but at just $35.00 and $8.00 for a can of spray paint, it looks just like one of these high end version. I chose to let some of the brass show through as it gave it an interesting patina.

We worked with Eminent Interior Design on this project. This mirror was one in which they purchased from a local "to the trade"
designer showroom. It was a high end mirror, but there are many sources
on line that might have something similar. Best, Peterssen/Keller
