Why Choose a Lab-Grown Diamond Necklace?

A lab-grown diamond necklace gives you the brilliance of a natural diamond at a more accessible price. Whether you are buying for yourself or marking a special occasion, our pendants and sliders are finished and ready to wear, with no long wait. Shop online with delivery across Australia, or visit our Westfield Chermside showroom to see them in person.

Each necklace is set with a lab-grown diamond, chemically, optically and physically identical to a mined diamond, with the same hardness, fire and lasting brilliance. Created in a laboratory rather than mined from the earth, lab-grown diamonds offer exceptional value without compromising on quality or beauty.

Find Your Necklace by Diamond Shape

Explore by shape

Each diamond shape carries its own character. Here is what is currently available across our necklace collection.

Round

Timeless and brilliant, cut to maximise light return. The classic choice for solitaire sliders and cross pendants.

Oval

Elongated and elegant, a soft, modern alternative to the round.

Pear

Distinctive and directional, with a tapered point that draws the eye.

Marquise

Elongating and bold, with pointed ends and a striking silhouette.

Emerald

Architectural and understated, with clean step-cut lines.

Metal, Settings and Styles

Metal

Our necklaces are crafted in 9ct yellow gold. If you would like a different metal for a custom piece, our team can talk you through the options.

Setting Styles

Styles range from bezel-set and claw-set solitaire sliders that sit close to the neckline, to fixed bezel-set pendants up to 2ct total diamond weight, a round diamond cross pendant, and pieces that pair lab-grown diamonds with South Sea or Keshi pearls. Each setting is designed to let the diamond do the talking.

Explore our lab-grown diamond earrings, bracelets and pearl jewellery to find a pairing that completes the look.
