While amethyst is known for its bright and bold purple coloring, a briolette cut shows off a more subtle glow, giving a lavender appearance for a beautiful look as seen on this 14k white gold necklace with briolette purple amethyst. This necklace, which makes a wonderful February birthstone gift, features a seven carat gem that really looks amazing when paired with any outfit, even the most casual clothing. It is set in 14k yellow, white, or rose gold that you select for the perfect look and includes a matching 18 inch box chain that is not only beautiful, but is high quality and durable.
