Arya 18K White Gold Accent Engagement Ring | Emerald Shape

Choose a setting, then pick its centre stone: a natural or laboratory-grown diamond, or a gemstone, in the size and grade you want. Add your ring size and we make the ring to order. You see the full price and delivery period before you pay.

Yes. Many of our settings also come as a pre-set ring with a laboratory-grown diamond, or with a moissanite centre stone, each at one complete price. Look for "More ways to own" on the ring's page.

Both are diamonds, with the same sparkle and hardness. A laboratory-grown diamond gives you a larger stone for the same budget; a natural diamond is rare and formed deep in the earth. A natural stone adds to the making time: 40 working days instead of 30.

Yes. A laboratory-grown diamond has the same chemical and optical properties as a natural diamond; it is grown above ground instead of mined. It usually costs less than a natural diamond of the same size and grade.

Where a diamond is certified, it comes with a report from an independent laboratory, such as IGI or GIA, and the diamond's details name the laboratory. A report is the laboratory's opinion of the stone. About grading reports

The open, step-cut facets of an emerald cut show the inside of the stone clearly, so many people choose a higher clarity grade, such as VS2 or better.

White gold is plated for a bright white finish, and over time the plating wears. Re-plating is a paid service, quoted before the work. Warranty and care

Almost everything we sell is made to order for you. A piece with a laboratory-grown stone (or your own stone) is delivered within 30 working days, and a piece with a natural diamond or gemstone within 40 working days, because natural stones are sourced and cleared by the South African Diamond and Precious Metals Regulator before we can set them. Add up to 10 working days for delivery outside South Africa. You'll see and confirm your delivery period before you pay. If we're ever going to be late, we tell you first, and you choose a new date or a full refund. Need it for an occasion? Tell us before you order. Full details

Yes. Delivery anywhere in South Africa is free, and it is signed for on arrival. If a parcel is lost on the way to you, we replace it at no cost. Shipping policy
