Three styles of heart pendant
Heart cut solitaire
A single diamond cut into the shape itself. It is the most classic and the most dependent on cutting quality: a good one has two even lobes, a visible cleft and a crisp point. Because the shape only reads clearly from about half a carat up, this style uses the largest stones.
Pavé or outline heart
Many small diamonds trace the outline instead. This gives a larger, more visible shape for less money and lots of sparkle from all the small facets. Open heart designs leave the center empty and feel light and modern.
Halo heart
A center stone, often heart cut, surrounded by a ring of small diamonds. The halo makes the center look larger and adds brightness, a good compromise between a solitaire and an outline.
Getting the details right
Check how the pendant hangs: a well designed diamond heart necklace sits upright rather than tipping forward. Look at the bail (the loop that holds the chain); a hidden or integrated bail looks cleaner than a large visible ring. For a pendant that will be worn daily, a bezel setting protects the point of the stone, its most fragile spot.
Lab grown or natural?
Lab grown diamonds let you choose a larger center stone for the same budget, which matters with this cut because the outline only shows well at larger sizes. Natural stones suit buyers who prefer mined origin. Once the pendant is on, the two are indistinguishable.

Budget guide
Near $290 you can find a delicate outline or a small diamond heart necklace that suits daily wear. Around $405 the pendant is clearly visible and the stones larger. Above $1,055 you move into heart cut solitaires of serious size and platinum.
For a gift, a diamond heart necklace in the recipient's usual metal on an 18 inch chain is the safest choice. If you are unsure of their taste, an outline reads as modern and light; a solitaire reads as classic and romantic.
Diamond Heart Necklaces: frequently asked questions
Is a heart necklace a good anniversary gift?
It is one of the most popular. A heart pendant carries an obvious meaning without needing a ring size, and a small diamond version can be worn every day for years.
Single stone or outline?
A solitaire is a single stone cut into a heart, best seen at half a carat and above. An outline or open heart uses many small stones to draw the shape and looks larger for the money.
What chain length suits a heart pendant?
16 to 18 inches suits most necklines. 16 inches sits at the collarbone; 18 inches falls just below it and is the most common gift length.
How much does a heart pendant cost?
The typical design here costs about $405, with most between $290 and $1,055. A single heart shaped stone of good size costs more than an outline of the same overall size.
What makes a good heart shaped diamond?
Look for a symmetrical outline with even lobes, a clear cleft and a sharp point. Heart shapes are best at around half a carat or larger; below that the shape is hard to see.
