A 1.36-carat rectangular octagonal lab-created ruby is a specific and unusual stone choice: the rectangular octagonal cut - a step-cut with clipped corners - reveals ruby's deep red through long, linear facets rather than the brilliant facets more commonly associated with colored stones. The result is a red that reads as rich and saturated, with depth that brilliant cuts scatter into sparkle rather than concentrate into color. Lab-created ruby carries identical chemical composition to natural ruby - corundum with chromium giving the red - at a price that makes the color accessible. A white zircon accent completes the setting cleanly. The rectangular form in a band ring is a genuine statement of contemporary design confidence.
