Scarcely – all too rarely – nature plots to create something truly heart-stopping in its grandeur. The 1,686.3-carat LKA and 1,438-carat Stephenson emeralds discovered in 1984 and 1969 respectively within the Hiddenite area are among the world's most spectacular stones, but distinguished gemologists esteem these two enormous, natural stones of astonishing crystal ranked amongst the largest emeralds ever found in the world: 

The LKA and Stephenson Emeralds.

An Unprecedented Opportunity

The Hiddenite area has produced some of the most exceptional stones of the last centuries, but when it brought The 1,686.3-carat LKA and 1,438-carat Stephenson rough emeralds into the hands of private ownership, they remained unsurfaced, safely secluded for decades.

Until now. 

The unveiling of these exceptionally large crystals of historical significance create the possibility of something truly remarkable – a moment of re-discovery and opportunity to appreciate a dual collection amongst the largest, rarest gems in the world.

"What does the artist do? He draws connections. He ties the invisible threads between things. He dives into history, be it the history of mankind, the geological history of the Earth or the beginning and end of the manifest cosmos."

- Anselm Kiefer
