This vintage piece is a bit contemporary and was most likely crafted sometime during the Modern design period ( 1980-2000 ). The necklace is 14k gold and is Italian made. The necklace features 4 different varieties of quartz. The chain is a designer style loop with a different fancy cut bezel set quartz set about every 1 & 1/2 inch. The chain measures approximately 30 inches in length making it super easy to just slip on, no clasp necessary.
