Sections of nacreous layer pearls cultured in Pinctada martensii (DÜNKER) were observed with electron microscope and the results were as follows: 1. Very thick conchiolin layer often deposited on surfaces of nuclei and small crystal grains were sometimes contained in the layer. These grains are considered as calcite. 2. In rare occasion, there were no deposition of thick conchiolin on surfaces of nuclei and nacreous layers, composed of aragonite and conchiolin, deposited directly on them. 3. Some pearls have three successive layers, -periostracum, prismatic and nacreous layers. 4. Thick conchiolin layers were also found in nacres, whose structure were different at above and below the layers.
