Our Quality Promise: Stone Sourcing, Setting Precision, and Final Inspection

When you invest in a Diamond Lab ring, you're choosing more than just beauty—you're choosing integrity, craftsmanship, and quality that lasts a lifetime.

We believe your engagement ring should not only look stunning, but feel meaningful and last forever. That’s why we obsess over every step—from sourcing your stone to the final polish before delivery.

Here’s what sets us apart.

Sourcing Stones You Can Trust

We work only with lab-grown diamonds and moissanite that meet our highest ethical and aesthetic standards.

• Lab-Grown Diamonds: Every diamond we offer is grown in a controlled environment using cutting-edge technology that replicates nature’s process. These stones are chemically, physically, and optically identical to mined diamonds—without the environmental harm or ethical concerns.

• Moissanite: Our moissanite stones are always D colour, VVS1 clarity, and sourced from world-renowned producers. Each one is hand-selected for its intense brilliance and fire.

We never work with low-grade stones or factory-bulk stock. Instead, we handpick each gem to ensure every Diamond Lab ring sparkles with confidence.

Hand-Set with Precision, Not Mass-Produced

Each ring is handcrafted in Australia, using traditional techniques and modern tools.

• No mass casting.

• No generic settings.

• No shortcuts.

Instead, we custom-make every setting to suit your chosen stone and design, ensuring a flawless fit and exceptional longevity.

Claw prongs are our standard—modern, secure, and elegant. We’ve phased out outdated bulky prongs that can overwhelm the centre stone. Whether you're choosing a solitaire or pavé design, your setting will be sleek, strong, and timeless.

Our jewellers pay obsessive attention to:

• Symmetry and alignment

• Prong tension and polish

• Band curvature and finish

• Pavé uniformity (for sidestones)

• Setting height and comfort

Because details matter—especially when you’re wearing it every day.

Final Inspection: Nothing Leaves Without Passing

Before any piece leaves our studio, it undergoes a final, multi-point inspection led by our senior jewellers.

We check for:

• Secure stone setting

• Prong alignment and polish

• Band symmetry and width accuracy

• Finish quality and surface shine

• Ring size accuracy

• Custom engraving or special additions

If a single detail isn’t perfect, it doesn’t go out. Period.

This level of care ensures every Diamond Lab ring not only meets luxury standards—it exceeds expectations.
