Pros, Cons, and Value Comparison
| Feature | Pro | Con |
| Curved “Smile” Design | Follows the collarbone contour beautifully, making it more comfortable than rigid bars. | As a shaped piece, it requires careful storage to prevent the chain or arc from kinking. |
| Bezel Setting | Highly durable; the gold border protects diamond edges and creates a smooth, snag-free feel. | The gold bezel adds visual “weight,” which can slightly mask the size of the stone compared to a prong setting. |
| Sustainable Luxury | Offers exceptional diamond quality and clarity at a more accessible price point than mined diamonds. | Being a high-end luxury item, this specific design may have limited availability. |
Design Highlights: Smile Necklace
A smile necklace features a curved bar of diamonds that mimics the shape of a smile. This design is highly sought after because it rests naturally against the collarbone, providing a fluid and flattering look.
Seven diamonds allow for a wide, expressive arc. By scaling the carat weight to 1.75 CTW, the necklace achieves a balance between being a visible statement piece and remaining delicate enough for everyday wear.
For an arc design, bezel settings provide a unified, liquid gold look. They ensure the diamonds are securely held along the curve, making the piece much less likely to snag on clothing compared to prong-set bars.
The 16-inch setting is ideal for a classic choker-style fit, while the 18-inch length allows for a slightly lower drape, making it perfect for layering with longer gold chains or pendants.
