GIA Certified Natural Madagascar Ruby & Diamond Platinum Three Stone Ring

A spectacular ruby with the paperwork to match.

This classic three-stone ring centers a GIA-certified natural ruby of Madagascar origin, flanked by a beautifully matched pair of emerald-cut diamonds and set in platinum.

The oval ruby displays a rich, saturated red color and measures 8.36 × 7.13 × 3.42 mm. GIA identifies the stone as natural corundum, ruby variety, transparent, with Madagascar geographic origin. The report notes that the ruby has been heated, a commonly encountered treatment for natural ruby.

Its cutting combines a brilliant-cut crown with a step-cut pavilion, giving the stone a beautiful combination of color, depth and flashes of light.

On either side, elongated emerald-cut diamonds provide the perfect contrast. Their crisp, linear facets and bright white appearance frame the ruby without competing with it, creating the timeless three-stone silhouette.

The setting is crafted in platinum, allowing the ruby’s intense red color to remain the absolute focus.

There is something especially compelling about the simplicity of this design: one exceptional colored gemstone, two diamonds and platinum. Nothing unnecessary.
