Birthstone
Spinel is the most recent addition to the official birthstones list. In 2016, the American Gem Trade Association recognized it as an alternative birthstone for August. Traditionally mistaken for ruby, spinel now stands proudly on its own, admired for its durability, vivid range of colors, and growing popularity in fine jewelry.
Gemstone Description
This grey spinel of 3.13 carats is a true rarity for collectors and bespoke jewelry lovers alike. Its antique cushion cut enhances the depth of its color—a dark, greenish-grey tone that shifts beautifully under different lighting conditions.

The gem’s understated elegance is elevated by its internal world: under the microscope, you’ll discover a fully formed spinel crystal encapsulated within. These solid inclusions not only confirm its natural origin but also reveal the intricate beauty of geological formation.

With good proportions and moderate clarity, this spinel is a perfect balance between character and refinement. The color behaves well under both natural and incandescent light, offering flashes of green, grey, and steel blue depending on the angle. Whether worn in a solitaire or surrounded by diamonds, this piece will shine with distinction.

A gem that is as captivating inside as it is outside—a reminder that nature often hides its most precious surprises within.
