Art deco 14k floral and diamond ring

This was a stick pin from the art deco era. This was originally a stick pin. I converted it into a ring. The band is 14 karat white gold, as is the top of the piece. It has a diamond that’s prong set and is original to the piece. It has an octagon double border around the diamond that has fine milgrain, in excellent condition. The outer ring is made up of small flowers. It is a spectacular piece that ended up in my jewelry box for years. But I found I’ve only worn it once. It is a size 7 1/4.
