This elegant necklace features baguette-cut amethyst gemstones complemented by 0.19 total carat weight of natural diamonds with VS2 clarity and I color grade. The piece is crafted in 14kt white gold (585/1000 fineness), providing both durability and a bright, silvery appearance characteristic of fine jewelry. The bar-style design combines the vibrant purple hues of natural amethyst, a variety of quartz prized for its bold color, with the brilliant sparkle of round diamonds.
The necklace includes an adjustable chain with multiple length options (typically 16", 17", and 18") secured with a lobster clasp closure for versatile wearing. The white gold setting showcases the contrast between the rich purple amethyst and the brilliant white diamonds, creating a sophisticated piece suitable for both everyday elegance and special occasions.
To maintain this jewelry, soak in warm soapy water and use a soft brush to remove dirt. Avoid wearing during strenuous activities to protect the setting and gemstones from impact damage.
