Rainbow Opal Necklace with Colored Gemstone Arc

This rainbow opal necklace is a joyful study in color, light, and fine craftsmanship. Custom designed and made by Sydney Strong, this 18k yellow gold necklace features a double prong set Australian opal accented by a carefully arranged arc of colored stones. Set on a 14k yellow gold 1.5mm cable chain, the necklace feels bright, artistic, and deeply personal, made for someone who loves jewelry with meaning and visual presence.

At the center of the design is an Australian opal, chosen for its natural play of color and luminous depth. Opal has a way of shifting as it moves, revealing flashes of light that can feel soft, fiery, watery, and electric all at once. In this necklace, the opal becomes the heart of the piece, giving the design a dreamlike quality while still feeling refined and wearable.

Surrounding the opal is a thoughtful rainbow of 11 round full cut colored stones. The arrangement includes pink sapphire, ruby, red diamond, orange diamond, poppy topaz, yellow diamond, green diamond, tsavorite garnet, aqua blue diamond, blue sapphire, and amethyst. Each stone adds its own voice to the necklace, creating a graceful spectrum of color that enhances the opal without taking attention away from it.

The 18k yellow gold setting brings warmth to the full design. Yellow gold pairs beautifully with rainbow opal jewelry because it softens the color palette while adding richness and polish. The gold gives the piece a timeless foundation, while the opal and gemstone accents keep it expressive, modern, and full of personality.

The double prong setting secures the Australian opal while keeping the shape of the stone visible and graceful. This kind of setting allows the gemstone to remain the focal point, with just enough gold to frame it beautifully. The 14k yellow gold 16-inch cable chain lets the pendant rest close to the neckline, making it easy to wear as a signature necklace or as a meaningful layer among other cherished pieces.
