Even more valuable than diamonds, fine-quality Emeralds of significant size are among the world’s most bewitching jewels.

Their incomparable dark green colour is produced only under extremely rare conditions. Because these conditions also result in tiny cracks and cavities in the stone, inclusions are allowed in top-quality Emeralds.

The hue of nature itself, Emerald enjoys appeal year-round: an ideal accent for spring wardrobes, a highlight of summer designs, an autumn complement and the perfect hue to dispel winter blues. Emerald has cross-generational appeal.

Emerald is the birthstone for May and is also the gemstone for the twentieth and thirty-fifth wedding anniversaries.
