Frequently asked questions

Yes. A lab-grown diamond is a real diamond: the same pure carbon crystal as a mined diamond, with the same hardness, sparkle and chemistry. The only difference is where it formed: in a lab instead of underground.

No. Every stone we use is a lab-grown diamond. Moissanite is a different mineral (silicon carbide) and cubic zirconia is a diamond look-alike. Neither is a diamond.

We use IGI-certified diamonds. The certification details for each piece are listed on its product page, so you can see what you are getting before you order.

IGI (International Gemological Institute) is an independent gem lab. It grades diamonds on the 4Cs: cut, color, clarity and carat weight. An independent grade means you are not relying on the seller’s word.

Yes. A standard diamond tester reads a lab-grown diamond as diamond, because it is one. Specialist lab equipment can tell lab-grown from mined, which is why lab-grown diamonds are always sold as lab-grown.

Where a piece offers a choice of diamond quality, the color and clarity of each option are shown on the product page. Our lab-grown diamond guide explains what the grades mean in plain words.

Yes. Diamond is the hardest material used in jewelry (10 on the Mohs scale), so it is made for daily wear. Like any fine jewelry, take it off for the gym, heavy work, swimming pools and cleaning products. See our jewelry care tips.
