Description
A lab-created opal heart with a shifting play of color sits at the center of this Cubic Zirconia heart necklace in sterling silver, ringed by multi-color sparkle. The sterling silver carries a rhodium finish that gives a bright white shine and a polished surface. The heart hangs from a fine cable chain that fastens with a spring ring clasp, and an extender lets you change where it rests. Wear it with an open collar shirt or layered under a longer chain for an understated evening look. A romantic pick for someone born in October.

Are these opal necklaces natural or lab-created?
The opals on this page are lab-created, not natural. Lab-created opal has the same soft play of color as mined opal and is made in a controlled setting. Natural opal is sometimes treated or backed, but that is a general point about opal, not about these pieces.
Which opal necklace style is best for everyday wear?
A small solitary pendant or simple circle suits daily wear best. Opal is softer than many gems, so a clean, low-profile design with fewer edges is easier to wear day to day. Pieces with an extender let you adjust the length for layering.
How should I care for an opal necklace?
Wipe it gently with a soft, damp cloth after wearing. Keep it away from harsh chemicals, perfume and hard knocks, and store it separately so the opal and sterling silver do not scratch. See our jewelry care guide for more.
Which opal necklace styles are most popular?
Cat, teardrop and hearts pendants lead the list. Plain opal pendants, circles with a heart and moon and stars styles follow close behind. Halo designs with cubic zirconia also appear often, and most are sterling silver on an 18 inch chain.
