Caroline's Jewelry with a Past is offering a 14kt. yellow gold early 20th. century carved lavender jadeite plaque necklace circa 1910-1920. This piece features three prong set, oval medium purple jadeite plaques. There are an additional two prong set, pendeloque shaped jadeite plaques. The jadeite is medium lavender banded and striated with a yellowish white. The larger stones are carved with a stylized flower on one side, while the pear shaped pieces are carved with a flower on both sides. The oval center plaque is 23.5mm X 17.5mm. The oval side plaques are 23.25mm X 15.5mm. The pendeloque or pear shaped plaques are 17mm X 11mm. The plaques are separated by yellow gold filigree diamond shaped chain. Each diamond is edged with a serrated edge and separated by rounded links. The necklace is 16" long.
From the early Art Nouveau period (around 1880) through about 1930, jade and jadeite carved plaques in all colors were imported from China where they had been used as decoration for about a century. The colors of jade and jadeite were perfect for the jewelry of that period. Jadeite colors can be white, green (apple green to deep green), blue green, yellow, pink, lavender and other more rare colors. Emerald green or "Imperial Jade", "Kingfisher" green, other greens and lavender are the most rare colors. Each color is created by trace elements, such as chromium and iron. The degree of translucence ranges from opaque to nearly clear. The higher the translucence, the more valuable the stone.
The gold content of this piece has been tested using standard accepted testing methods, such as acid testing. The piece is marked "14kt." The jadeite was tested using a standard jeweler's gemstone tester and shown to be jadeite, not amethyst. The sizes were calculated using a standard jeweler's caliper. The stones were not removed from the piece to do physical testing or for weight. The carved jadeite is naturally colored without dye. There are natural inclusions in the stones. The jadeite in this piece has medium translucence.
