One perfect, sparkling diamond on a chain, simple and classic, yet commanding in all the right ways. A diamond solitaire necklace is a must-have piece that works with everything and everyone. In this guide, we’ll cover carat sizes, cuts, settings and chain lengths so you can find the necklace that’s just right, whether keeping it or giving it.
What Is a Diamond Solitaire Necklace?
A diamond solitaire necklace is a simple, iconic and versatile piece featuring a single diamond on a chain, no extras, no accents, just the stone front and center. It’s the kind of necklace you can wear with anything, and because the design is so clean, the focus stays entirely on the diamond, making it a go-to piece for everyday wear.
Diamond Solitaire Necklace Carat Sizes
0.5 Carat Diamond Solitaire Necklace
At 0.5 carats, the diamond feels light, wearable and just sparkly enough. It’s a comfortable size to wear on its own and especially great for layering with other necklaces.
1 Carat Diamond Solitaire Necklace
A 1-carat solitaire is the classic for a reason. It’s the “can’t-go-wrong” size: timeless and flattering on any neckline. If you want one necklace that does it all, this is it.
1.5 Carat Diamond Solitaire Necklace
A 1.5 carat diamond solitaire offers a step up in size and shine. It’s noticeably larger than the classic sizes but still easy to wear with everything.
2 Carat Diamond Solitaire Necklace
With a 2-carat solitaire, you get a generous amount of sparkle in a design that stays minimal. It’s the kind of piece that naturally draws attention while still keeping the simplicity and elegance of a traditional solitaire.

Diamond Solitaire Necklace Settings
The setting can completely change the look of your necklace and how it wears over time. Most solitaires come in two common styles: prong and bezel, but some designs add a halo of smaller diamonds around the center stone for extra sparkle.
Prong Set Diamond Solitaire Necklace
The diamond is held up slightly, giving you the most sparkle.
Bezel Set Diamond Solitaire Necklace
A thin rim of metal surrounds the stone, which creates a smooth, contemporary style and provides extra protection for everyday use.
If you’re gifting, bezels are perfect—they appeal to almost everyone and are very wearable.
Halo Set Diamond Solitaire Necklace
A halo, though not a true solitaire, creates a larger look without a big price increase.
Diamond Solitaire Necklace Chain Length
Most solitaires sit on a 16″ or 18″ chain:
- 16″ rests higher on the collarbone, perfect for layering.
- 18″ sits a bit lower, classic and universally flattering.
If layering is the plan, mixing lengths creates dimension without tangling.
