SummaryThe paper embodies a study of the structure of the material composing pearls and of the optical effects which they display. The following topics are dealt with: (1) Birefringence, (2) X-ray-diffraction patterns, (3) The reflection-diffraction spectra, (4) The diffusion haloes of reflection and transmission, (5) The whispering-gallery effect, (6) The spectral character of iridescence and the influence of birefringence thereon, (7) The transmission spectra. The most noteworthy result of…

Influence of microstructure on optical behaviour of freshwater cultured pearls
Abstract The relationship between optical behaviour and microstructure of pearl was studied by laser scanning confocal microscopy, high resolution scanning electron microscopy and atomic force
On the chromatic diffusion halo and other optical effects exhibited by pearls
SummaryThe paper discusses the origin and character of the coloured diffusion halo exhibited by pearls surrounding the reflected image of a light source seen at their surface. Twelve photographs
Natural Pearls
TLDR
Replicating Jameson’s choice of samples, it is described the more spectacular structural changes in the mineralization of pearls associated with two instances of cell specialization: toward producing one shell material – in the event of natural pearl nucleation, or switching between two in later pearl growth.
The Quality Characteristic of Pearls Produced at Pearl oyster, Pinctada fucata cultured in Tongyeong
TLDR
The result is to provide scientific data for the value of pearl from Korean seawater and it is clear that 407 nm, 430 nm and 460 nm peak are White group that are not in processed condition.

X-ray analysis of the structure of iridescent shells
X-ray diffraction patterns of the nacreous layer of iridescent shells have been obtained using a monochromatic X-ray beam incident along various directions. From a study of these patterns it is found
