Traditional Princess cut Diamond Halo Engagement Ring

Agatha is our traditional Princess cut Diamond Halo Engagement Ring, providing a feel of elegance in every detail. The central Princess cut Diamond is held within a secure four claw setting and encircled by a halo of an additional 0.15cts of Round Brilliant cut Diamonds. The plain and slender shoulders enhance the luxury of the central Diamond along with the diamond halo. This design also boasts a Wedding Ring friendly setting, opening it up to a wide range of Wedding Ring styles when the time comes. This ring is also fully customisable, from the precious metal it is created, to the full specifications of the Diamond, including its carat weight, colour and clarity (both available from the drop-down menu above). Once we have created your ring to your exact specifications, it will then be delivered straight to your door in our discreet packaging with the addition of a small proposal ring box, perfect for a surprise proposal.

Discover what's inside the box

When we send your parcel to USA, we securely wrap the secure outer box in a plain white outer wrapping. Inside you will discover a solid outer box containing a presentation box with engagement ring with an additional pocked ring box. All documents including certification are enclosed within the additional document wallet located in the separate section of the main box. We pride ourselves on luxurious packaging as part of your experience.
