I was at 
Reeds last weekend getting my sister's engagement ring cleaned and saw a really lovely ring by 
Facets. It is essentially a diamond with a halo of smaller diamonds, but the shape is reminiscent of the flower rings - not just a perfect circle. This one is #
8808 with a 1ct center stone, numbers 
8804, 
8806 and 
8810 are the same style in different sizes.
Hearts on Fire makes a very similar ring, the Beloved Solitaire. I'm not quite sure how it's a solitaire when it includes so many diamonds, but maybe that means it doesn't have diamonds on the band? Either way, it's gorgeous! 
Leigh Jay Nacht in New York has an antique ring, circa 1950's, with a similar feel. They call it the 
R365 Cluster Ring. $5,400.
