0.5 Carat Diamond Necklace: Half Carat Solitaire Pendants

One diamond, half a carat, on a fine chain: that is a 0.5 carat diamond necklace in its classic solitaire form. A round of that weight is about 5.2 mm across, large enough to be noticed across a dinner table and still subtle enough for the office. The choices that shape it most are the chain length and how the stone is held.

FAQs

Elongated shapes. Ovals, pears and marquises spread their weight over more length, so they face up larger than a round of the same carat weight, and on a pendant that length draws the eye down the neckline. A round gives the most sparkle per stone, so the choice is between size on the skin and pure brilliance.
