Hexagon Alexandrite Ring- Sterling Silver

A round brilliant alexandrite that cannot decide what color it is, held inside the hexagonal halo this ring is named for. The center shifts across purple, teal, and blue as the light around it changes, and the six-sided frame — 10.5 mm across, edged in simulated diamonds — gives that shifting color a hard geometric border to push against. Built on solid 925 sterling silver with a rhodium finish.

Purple, Teal, Blue — in the Same Stone

Most color-change stones manage two states. This alexandrite runs a wider range: a cool teal-blue under daylight and bright LEDs, warming through to a distinct purple under incandescent bulbs and candlelight. The stone is not doing anything — it absorbs the green and red parts of the spectrum unevenly, so your eyes read whichever survives in the light you are standing in. A brilliant cut is the right choice here because it bounces light through the maximum volume of stone, which makes the shift more pronounced than a step cut would. Our journal covers the mechanism in does synthetic alexandrite change colors.

Lab-Grown, and Genuinely So

Alexandrite was first identified in the Ural Mountains of Russia in the nineteenth century, and natural material has been scarce ever since — scarce enough that a natural stone at this size would price the ring far out of the range most people are shopping in. This center is lab-grown alexandrite: the same mineral, the same optical behavior, the same 8.5 on the Mohs scale, produced reliably rather than found by luck. Our guide to lab-grown vs natural alexandrite lays out what actually differs, and the alexandrite guide covers what to look for in a color shift.

The Hexagon Halo

A halo does two jobs: it makes a modest center read larger, and it gives the eye a bright border that intensifies the color inside it. Here the halo is hexagonal rather than round, which is the detail that separates this ring from every other halo design — six straight edges around a round stone create a deliberate tension between the geometric frame and the soft circle at its middle. At 10.5 mm across the halo carries real presence on the finger, while the 6.0 mm center stays at an everyday scale.

Sterling Silver, Rhodium Finished

The band is solid 925 sterling silver, 2.3 mm on average and comfort fit, with a rhodium finish over it. Rhodium is a platinum-group metal, and finishing sterling with it gives the silver a brighter, whiter luster and an added layer of protection on the surface — a standard we apply across our sterling range. The ring is also nickel-free and hypoallergenic. Read what 925 sterling silver means for the standard in full, and browse more in sterling silver engagement rings.

June's Stone, Vintage Framing

Alexandrite is one of June's birthstones, and the vintage-inspired detailing here — the close-set accent stones, the geometric halo, the slim band — borrows from antique jewelry rather than contemporary minimalism.

Sizing & Care

The ring is made in the size you select, so measure with our ring size guide before ordering, keeping in mind that a comfort-fit band can feel slightly snugger than a flat band of the same nominal size. For care, wipe the ring with a soft, dry cloth after wearing and use a soft brush around the halo where skin oils collect. Keep it away from household cleaners and chlorinated water, and store it dry. Our guide to cleaning sterling silver covers the routine in more detail.
