Yes. Many of our clients choose to purchase a certified loose lab diamond and either have it set later or keep it as an investment stone.

How long does delivery take?

Delivery times vary depending on the stone’s location. Many diamonds are available within 7–14 days, while special orders may take longer.

Are your lab diamonds certified?

Yes. Every stone we offer comes with an official IGI or GIA grading certificate for guaranteed quality and authenticity.

Absolutely. Our gemmologists can guide you through the selection process, providing recommendations based on your design, budget, and preferences.

Do you ship across Australia?
