Abstract
NON-TECHNICAL SUMMARY: The color of nacre is one of the most significant criteria in determining the value of a pearl. Nacre color is due to both schemochromic phenomena and biochromes (pigments). The vast majority of pearl farm profits comes from the small percentage of pearls that have a perfect surface, good color, and high luster. Even small increases in these quality factors can radically increase profits. Positive results from this work will allow us to gain some control over these important characteristics and produce higher value pearls. This patentable technology would increase the profitability of BPI affiliated farms, and allow additional income through licensing agreements with other farms.
