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?
We ship free and fully insured to the USA, UK, all EU countries and Australia. Jewellery takes 7-12 business days to make and 3-5 business days to arrive.
Will I pay import duty or VAT?
Possibly. Each country sets its own rules for diamonds and jewellery. Unless checkout says duties are included, the courier collects any duty or VAT on delivery. We always declare the true value.
Can I return my order?
Yes, within 30 days of delivery for a full refund, if the piece is unworn and comes back with its certificate. Engraved and custom-designed pieces can be returned only if faulty.
How do I pay?
By card, Apple Pay or Google Pay through a secure payment page, or by bank transfer for larger orders. For diamonds we confirm the exact stone with you before payment is taken.
Why buy diamonds from India?
Surat in India cuts and polishes the large majority of the world's diamonds by volume. Buying from a maker there removes importer and wholesale margins, which is why prices are lower than at most high-street jewellers.
