Below is the description of the solitaire but this page and link is for the pendant. 

The CvB  delightful "Dahlia" style solitaire combines elegant simplicity with a light & feminine flair for a uniquely gorgeous alternative to a simple six or eight prong setting. Shown here with a millegrain detail knife edge shoulder.

This solitaire offers you the ability to add customizations, such as a pave shank; two tone metal combinations, or a six or eight prong head styling.
