Diamond Heart Necklace

Show that love is eternal with a diamond heart necklace. Jewelry with diamonds is a wonderful gift for romantic occasions such as weddings and anniversaries. The cool, clear shine of diamonds is neutral enough to wear with outfits of any color.

This precious stone is a symbol of timelessness and adds glamorous sparkle to any look, from casual to formal. Find necklaces and other jewelry from Sweethearts, EFFY Collection and many more.

Choose a diamond necklace as a finishing touch for formal occasions. The stones glint in the light with every movement—perfect for a night of dancing. Diamond necklaces are available in a wide variety of styles, including long and short chains as well as pendants. Want to show love in a sweet and stylish way? Slip a heart-shaped pendant on and wear it proudly! From tiny diamond-dotted heart outlines to bold sterling silver cut-outs, there are pendants of all varieties out there waiting to be discovered.

A silver necklace features true neutral coloring. Silver captures and enhances all of the colors around it, reflecting them back beautifully. Choose a diamond heart necklace in silver for a double dose of shine. Let one large diamond be the center of attention, or dazzle the eyes with dozens of tiny stones encrusted over the surface of the necklace. Necklaces in sterling silver are stainless, so they will not tarnish or discolor with age.

Want some subtle contrast? Opt for a gold necklace with diamonds. The warm tone of gold and the icy clarity of the stones work together to create complexity, resulting in a versatile piece of jewelry that looks great with a wide variety of colors. Pair gold jewelry with dark blue clothing to enhance the warmth of the metal. Hunter green and wine red also complement golden accessories. White gold necklaces with heart pendants are also available for a cooler-toned gold option.

Find a beautiful diamond heart necklace today at Macy's.
