The best chain lengths for a 1 carat diamond necklace are 16, 17, and 18 inches. An 18-inch chain is the most popular, resting perfectly on the collarbone. Shorter 16-inch chains sit slightly higher for a classic look. In our 30 years of making fine jewelry, we find these lengths keep the gem safe and visible. A smart lab-grown stone shines best when it catches the light right at your neckline.
