Opal Necklaces

An opal necklace carries a whole spectrum in one stone, that shifting play of blue, green, and pink that no two opals share. This collection runs from milky white cabochons to warm Mexican fire opal, set as pendants, crosses, and hearts on gold and sterling silver. Each piece comes complete at one all-in price, with any accent diamonds genuine and lab-grown.

Opal is October's birthstone, which makes any of these a natural birthday gift; pair one with opal earrings for a set, or reach for a diamond pendant when you want something harder-wearing. Chain lengths and metals vary so you can layer or wear a single statement piece.

Here is the honest part: opal is soft, a Mohs 5.5 to 6.5, and it holds a little water inside, so it needs more care than a diamond or sapphire. We favor bezel and protected settings that shield the girdle, and we keep opal off ultrasonic cleaners and away from sudden heat, which can dry and craze the stone. A wipe with a soft damp cloth is all it wants.

Every necklace is made to order and shipped fully insured at no cost, with a 30-day return window and a lifetime warranty on the setting. Prefer a specific opal color, a larger cabochon, or a longer chain? Our concierge will hand-select the stone and confirm it before you order; the make-to-order timeline is shown on each product page.
