Six designs for brooches with stylized flowers and leaves, red stones, diamonds and pearls

Drawing with six designs for brooches, part of an album of drawings in pen and ink of designs for jewelry in the style of the French School of the 19th century, designed for the French jewelry house Mellerio-Borgnis. The first design consists of a bundle of long, scrolling, stylized, green leaves, a large, silver, stylized flower, and gold branches with round pearls. The second consists of a stylized bundle of grapes made up of large, stylized, green leaves and round, red stones. The third consists of a gold ribbon bow holding a bundle of stylized, green leaves, pearls, and a stylized, silver flower, from which hangs a large, teardrop pearl. The fourth design consists of a small, gold crown with rectangular alternating rubies and emeralds, flanked above by round pearls, over a green ribbon bow with a round pearl in the center from which hangs a large, red, round stone, flanked by four small trefoils of gold, and with a hanging teardrop pearl on the bottom. The fifth design consists of a gold scrolling motif with an interlacing garland of stylized, green leaves and round pearls, and a large, round, red stone. The final design consists of two large, stylized, green leaves, from which hang smaller, thinner, stylized leaves and round pearls. The green areas of the designs might have been achieved using enamel or small, green (semi-) precious stones in the manufactured jewels; the red stones could have been corals, rubies, or colored glass.
