The world of fine gemstones is defined by rarity, beauty, and provenance. One of our finest emeralds recently made waves at Phillips Geneva Jewels Auction: THREE, where a 20.49-carat Colombian emerald ring sold for an impressive CHF1,330,500—far exceeding its original estimate of CHF650,000–850,000 (US$750,000–1,000,000).
What makes this emerald so exceptional?
A Gem of Unparalleled Rarity
Colombian emeralds have long been considered the finest in the world, prized for their luminous green hues and superior crystal quality. However, finding one over 20 carats with no indications of clarity enhancement is extraordinarily rare. Almost all emeralds undergo some degree of oiling to reduce the appearance of natural inclusions, making an untreated specimen of this size a true collector’s gem.
Accompanied by SSEF and Gübelin reports, this emerald was certified as a natural Colombian stone, entirely free of enhancements—a distinction that underscores its rarity and desirability among serious collectors.
More Than an Investment: A Statement of Elegance
Beyond its exceptional characteristics, this emerald ring is a statement of strength, sophistication, and individuality. Its mesmerising depth of colour and striking step-cut silhouette make it a bold, timeless piece that commands attention.
