The emerald cut diamond
The emerald cut uses long, flat step facets instead of the brilliant facets of a round. Rather than sparkle, it gives broad flashes of light and a clear "hall of mirrors" look into the stone. Its long shape and cut corners give a quiet, elegant ring that looks larger than its weight. The halo follows the outline of the emerald diamond, so the shape reads clearly from across a room.
Why a halo?
A halo frames the centre diamond with a ring of small diamonds. The extra sparkle makes the centre stone look larger, so it is a good way to get a big look for less. Paired with a diamond-set band, it gives the most sparkle of all.
Why platinum?
We use 950 platinum, hallmarked in the UK. It is about 95% pure, so it is naturally white all the way through and never needs re-plating. It is heavier than gold and very hard-wearing: rather than wearing away, the metal moves over time and takes on a soft satin look, which a quick polish brings back to a high shine. It is also the best choice if you have sensitive skin.
Choosing your emerald diamond
The open step facets show more of the inside of the stone, so clarity matters more than on a round: VS2 or better is a safe choice. A ratio of 1.30 to 1.50 gives the classic shape. The cut corners protect the stone, so it is a practical choice for everyday wear.

Frequently Asked Questions
VS2 or better is a safe choice. Step-cut facets are open and flat, so inclusions are easier to see than in a brilliant-cut diamond. Check the stone's photos before you choose.
Yes. The ring of small diamonds adds to the spread of the centre stone, so it looks noticeably larger than it would on its own.
All precious metals mark with wear. Platinum moves rather than wearing away, so it keeps its weight and holds the diamond securely. Over time it takes on a soft satin finish, and we can polish it back to a bright shine whenever you like.
Yes. Every ring can be set with a natural or lab-grown diamond from our live stock. Both are real diamonds; lab-grown stones cost less for the same size and grade.
