Why set an emerald cut diamond east-west?

Turned sideways, an emerald cut covers more of the width of your finger and less of its length, so it reads as a horizontal line rather than a long one. The step facets run across your hand, and the ring looks less expected than the same diamond set north-south. Any shape with a long side can be set this way; the emerald cut shows it most clearly because its corners and steps are straight.

What is a trillion diamond?

A trillion is a triangular diamond. Set beside a center diamond with one flat side facing it, a trillion continues the outline of the center and ends in a point, so the three diamonds read as one shape. Beside a step cut like the emerald, the straight edges of the trillions keep the whole ring geometric.

What wedding ring fits beside the Sloane?

The center sits at a medium height on cathedral sides, so a slim flat band can sit close beneath it. If you want diamonds in the wedding ring as well, the Reese's flush-set dome stays low, and a contoured band like the Zoey follows the outline of the setting. Bring the ring to a design appointment and we can try the pairings on your hand before deciding.

How Lisa helps you refine your design before it is crafted.

Every Lisa Robin ring is made to order, so your design can be refined even when you order online. Whether you adjust one detail or reshape the design, Lisa guides you through each choice so the finished ring feels cohesive and entirely yours.

The Sloane East-West Emerald Cut Three Stone Engagement Ring

The Sloane East-West Emerald Cut Three Stone Engagement Ring

A three stone ring is usually read as past, present and future, laid in a row along the finger. The Sloane keeps the three and changes the direction: the emerald cut center turns sideways, so its long, mirror-like steps run across your hand instead of along it.

The trillions finish each end with a point. Their flat sides face the center, so the three diamonds read as one shape, wider than it is tall.

Cathedral sides lift the setting to a medium height, enough to show the profile without standing far above a wedding ring. It sits beside a slim flat band, a contoured band, or a domed band of diamonds and keeps its line with each.
