The Martha
The Martha 0.8CT Round Cut Alexandrite Three Stone Ring
Meet The Martha 0.8CT Round Cut Three Stone Alexandrite Ring, a piece that’s all about timeless elegance and a little touch of magic.
At the center of this ring is a 0.8-carat round Alexandrite, a gemstone that’s anything but ordinary. It shifts from greenish-blue in daylight to purples and reds under softer lighting—it’s like having two rings in one! On either side, you’ve got two brilliant lab-grown diamonds, adding extra sparkle to this meaningful three-stone design.
Crafted with a classic 6-prong setting, the Martha is as durable as it is stunning. And when it comes to the band? You’re spoiled for choice. Pick from Platinum Vermeil, 18K Gold Vermeil, 18K Rose Gold Vermeil, or go all out with Solid 14K Gold in yellow, rose, or white.
