Our diamonds
We offer two kinds of diamond and hold them to one standard. You choose the origin. We make sure the stone is worth choosing.
Two origins
| Laboratory-grown | Earth-mined | |
|---|---|---|
| What it is | Diamond grown from a diamond seed by HPHT or CVD | Diamond formed naturally deep underground |
| Look and hardness | Identical | Identical |
| Grading report | IGI, full 4Cs | IGI or GIA, full 4Cs |
| Price for the same grades | A fraction of earth-mined | Higher, with an established resale market |
| Setting, hallmark, box | Same | Same |
Our minimum standard
- Round brilliants cut Excellent. Fancy shapes chosen for proportion and by eye.
- Colour D to G and clarity VS2 or better as standard; VS1 or better for step cuts.
- An independent grading report for every diamond over 0.30 ct, sent to you before you pay.
- Earth-mined diamonds sourced under the Kimberley Process and the System of Warranties.
Plain disclosure
We always tell you which kind of diamond you are buying. It is stated on the product page, your order confirmation, your receipt and the grading report. We never use vague terms.
What we do not do is put the origin on the outside. The box, the pouch and the presentation card carry the Audley name only, whichever diamond is inside. Who you tell is up to you.
