NEW YORK – On Tuesday, April 19, starting at 2 pm Eastern time, Jasper52 will conduct a sale entirely devoted to pearl jewelry. Boasting 194 lots, Fine Pearl Jewelry delivers dozens of variations on the venerated gems of the sea, in color, shape, origin and jewelry design. Traditional white, round pearls are available in the form of a double-strand saltwater Akoya pearl necklace, but the auction lineup shows that pearls provide their own lustrous interpretation of the rainbow.
