A purple and white drop 3-bead necklace with an 18" adjustable chain is a vibrant and elegant piece of jewelry. The design features three beads arranged vertically, often in a graduated drop style. The beads are a combination of purple and white, creating a striking contrast. The purple beads may range in shades from deep violet to soft lavender, while the white beads giving them a smooth and lustrous appearance.

Each bead is carefully crafted, with the colors harmonizing to create a balanced yet eye-catching look. The three-bead drop design adds a sense of movement and elegance, as the beads taper down towards the center of the necklace, drawing attention to the neckline.

The 18-inch adjustable chain, usually made from silver or a complementary metal, provides versatility in wearing. It allows the necklace to be styled as a short statement piece or slightly longer for a more relaxed look. This necklace would be perfect for both everyday wear and special occasions, combining bold color with a sleek, minimalist design.
