What characterizes a graduated strand necklace?

A graduated strand necklace is characterized by having the largest pearl at the center, which then tapers to smaller pearls towards the clasp. This design creates a visually appealing graduated effect that draws attention to the centerpiece of the necklace. The increasing and decreasing size of the pearls provides a seamless flow and enhances the overall aesthetics of the piece, creating a sense of elegance and grace.

In this case, having the largest pearl in the center allows it to become the focal point of the necklace, while the smaller pearls framing it help to enhance its prominence. This style is typically seen in various types of necklaces, including those made with pearls and other types of beads, where the graduation in size adds depth and texture to the design.

The other choices do not correctly describe a graduated strand necklace, as they refer to uniform sizes or different placements of the larger pearls that would not achieve the same visual effect.
