The discernment research of a goldish pearl

About the change of the spectrum pattern by colouration

Abstract

I discuss those spectra patterns about the representative "colour and tone" sample of the goldish pearl of an Akoya pearl.
I indicate those spectrum patterns by choosing the several kinds of orangish and yellowish dispersion-dye.
Then I discuss what kind of influence to each "spectrum-patterns" is exerted mutually about these samples goldish pearls coloured with those dispersion dyes.
Furthermore I discuss even the result of the wilt test of the sample coloured pearl.
