Using the unique capabilities of HST NICMOS, we have obtained 2 µm coronagraphic polarimetry and 1 µm coronagraphic imaging of primordial circumstellar disks around several Herbig Ae stars. These data both clarify disk geometry and reveal distinctly different dust scattering properties around different sources, largely consistent with grain growth to larger sizes around older sources. We here present our coronagraphic images of these disks, and summarize our ongoing analysis and modeling efforts
