Natural Black Diamond, Blue Sapphire and 18ct Yellow Gold Necklace
A striking combination of natural black diamonds, vibrant blue sapphires and solid 18ct yellow gold creates this luxurious, contemporary necklace. The rich contrast of colour and fine detail gives the design a distinctive elegance.
The necklace features evenly sized black diamond beads, creating a smooth, balanced line of rich, dark sparkle. In addition, solid 18ct yellow gold spacers and sapphire beads introduce beautiful touches of colour and warmth.
At the centre, a polished 18ct yellow gold bulb setting holds a magnificent 0.85ct round brilliant faceted natural blue sapphire. Its bright, intense blue colour provides a wonderful contrast with the surrounding gold.
Furthermore, 22 natural white diamonds, form a delicate frame around the sapphire. David sets these diamonds into the gold, creating a perfect, sparkling border. Their combined weight is 0.22ct, adding brilliance without overwhelming the central gemstone.
The Beauty of Natural Blue Sapphires
Natural blue sapphires belong to the corundum family. Their beautiful blue colour comes from tiny amounts of iron and titanium within the crystal.
As a result, sapphires display an extraordinary range of blues, from delicate pastel shades to deep, rich tones. In particular, fine bright blue sapphires are highly prized for their lively colour and brilliance.
Moreover, sapphire’s excellent hardness makes it a superb choice for fine jewellery. Discover more about these remarkable gemstones in the GIA Sapphire Guide.
