ARC STEP East-West Emerald-Cut Lab-Grown Ruby Signet Ring

ARC STEP by MISSISSI places an emerald-cut lab-grown ruby east-west within a narrow bezel, bringing a broad rectangle of red across the finger. Two straight channels of baguette-shaped white lab-grown diamonds follow the shoulders of a tapered signet band. Polished metal frames the stepped facets, while the continuous shank rounds beneath the finger.

The selected center-stone design target is approximately 10 × 8 mm. This is a made-to-order starting specification, not a measurement taken from a finished ring. Choose 14K yellow gold, 14K white gold, 18K yellow gold, 18K white gold or platinum, with US ring sizes 4–11 in half-size steps.

Product Specifications

Design and Styling

ARC STEP combines a signet silhouette with the straight lines of step-cut stones. The ruby's longer dimension runs across the finger, and its clipped rectangular corners sit within a closely drawn metal frame. The diamond channels continue the geometric language along both shoulders without adding a halo around the center.

The broad face gives the ring presence as a single piece. Yellow gold offers a warm contrast to the red center; white gold and platinum create a cooler frame around the ruby and white accents. Pair it with a simple band or wear it alone so the uninterrupted shoulders and horizontal setting remain visible.

Made to Order by MISSISSI

Select your metal and ring size separately. The approximately 10 × 8 mm center is the starting target for this design. Actual stone selection, shoulder layout and final construction are reviewed before production. The finished dimensions depend on the selected ruby and the ring size.

A broad band can feel different from a narrow ring. If you are uncertain about your size, contact our Jewelry Concierge before ordering. For an unlisted size, personal engraving or another design adjustment, explore MISSISSI customization. Feasibility, specifications and any change to the price or preparation time are confirmed before you purchase.

Gemstone Details and Documentation

The red center is a lab-grown ruby; the white shoulder stones are lab-grown diamonds. Emerald cut describes the ruby's rectangular stepped-facet shape, not its gemstone identity. The design has two diamond-set channels, with multiple accents rather than one large diamond on each shoulder.

Carat weights, exact accent counts, gemstone grades and treatments are not specified here. A face-up dimension does not establish carat weight. No particular laboratory report or certificate is promised. Ask what documentation is available and included for your selected stones before ordering if this matters to your purchase.
