We report here some very interesting optical textures exhibited by a pure cholesterogenic compound viz., Cholesteryl-do-decyl carbonate. It also exhibits ringed spherulitic texture when crystallized at different temperatures. The observed ring spacing is found to increase with the increase of crystallization temperature and we were also able to determine Avarami's constants by studying the growth rate of these spherulites. Light scattering and optical diffraction studies have been carried out using optical textures exhibited by the sample. The local order parameters corresponding to untwisted nematic structure in the cholesteric layer has been estimated at various temperatures in the cholesteric phase using the measured refractive index and density data.
