Description
A 10K yellow gold heart-shaped pendant featuring a prong-set oval opal with diamond accents, cast in solid gold with a polished finish.
Opal is prized for its phenomenon effect - a shifting play of color that moves across the stone as light hits it from different angles, a trait unique among gemstones. Long associated with October birthstone tradition, opal has been worn since Victorian times as a symbol of hope and purity, and remains a popular choice for personal and sentimental jewelry.

Are the opals in these pendants real or treated?
The opals in the sample titles are lab-created. Lab-created opal is real opal material grown in a controlled setting, with the play of color of its natural cousin. Natural opal is sometimes treated, for example with oil or sugar smoking, so ask about any natural stone you buy elsewhere.
What affects the price of opal pendants?
Metal, size, and added stones drive the price. Sterling silver and 14K gold differ, as do pendant size in millimeters, opal inlay versus a single stone, and accents like cubic zirconia or diamond. Use the Price filter on this page to set a budget.
Which opal pendant styles are most popular?
Crosses, hearts, and slide pendants lead the list. Opal and cubic zirconia necklaces in halo, bail, and teardrop shapes follow closely. Animal and nature motifs such as starfish, turtles, dolphins, and palm trees also appear near the top.
What is a slide pendant, and how do I wear one?
A slide pendant has an open loop that threads onto a chain. It glides along the chain instead of hanging from a fixed ring. Several seahorse, starfish, and paw print styles here are slides, so you can switch chains easily.
How do I care for an opal pendant?
Wipe it gently with a soft, damp cloth. Opal is softer than many gems, so keep it away from harsh cleaners, hard knocks, and heavy scrubbing. Store it separately in a soft pouch. See our jewelry care guide for more tips.
