Questions buyers ask

Are lab-grown diamonds real diamonds?

Yes. A lab-grown diamond is pure crystallised carbon with the same hardness, refractive index and chemical structure as a mined diamond. Gem labs such as IGI and GIA grade them with the same colour, clarity and cut scales, and the report states that the stone is laboratory-grown.

How much cheaper is lab-grown than natural?

For the same size and quality, a lab-grown diamond usually costs a small fraction of a natural one. On our current price list a 1 carat round F-G VS lab-grown diamond is A$630 and a comparable GIA-graded natural diamond is A$7,850.

Which certificate comes with my diamond?

Lab-grown centre stones and loose stones come with an IGI report. Natural diamonds of 0.30 ct and above come with a GIA report. The report number is laser-inscribed on the girdle, and we send you the report before we charge.

Do you ship to my country, and how long does it take?
