    AUD $4,400.00 incl. GST

    Craving a piece that’s playful yet elegant? This diamond sapphire necklace in 18kt rose gold brings the best of both worlds. Its vibrant hues and sparkling diamonds light up any outfit.

    Features

    • Gemstones:
    – 87 round brilliant diamonds = 0.50ct
    – 25 princess cut sapphires = 1.66ct total, arranged in a full rainbow

    • Metal: Luxurious solid 18kt rose gold, polished for lasting warmth

    This necklace pairs a circle pendant with a mesmerising swirl of multicolour sapphires. The outer rim shimmers with diamonds, giving it a radiant halo. Two bezel-set diamonds along the chain add extra flashes of light.

    Style It Your Way

    Wear it alone for a bold pop of colour. Or layer it with rainbow sapphire hoop earrings to create a playful stack. Thanks to its rainbow palette, it works with everything — from casual tees to cocktail dresses.

    Why Choose This Diamond Sapphire Necklace?

    Each sapphire is carefully set to ensure seamless colour flow. The diamonds are hand-selected for their brilliance, while the 18kt rose gold brings a soft glow that flatters every skin tone. When you buy from Ernesto Buono, you also get personal service and craftsmanship you can trust.
