  • Catalogue Essay

    Graff Diamonds was established by Laurence Graff in 1960 at the mere age of 22, a prodigy who came to shape the world of high jewellery for almost six decades. He was one of the first to position high jewellery as a retail business and developed this into a vertically integrated empire which is very rare in the jewellery industry. Graff oversees each stage of the production, from mining, cutting and polishing, design to execution, closely monitoring to deliver the level of excellence the House is known for.

    Emeralds pulled from the earth of Colombia have long been heralded for the exceptional colour and quality. Today, gem connoisseurs still agree to this very fact and Colombian specimens of intriguing colour and fine clarity demand sky-high prices. This is no surprise because no other place in the world possesses such geological environment for the formation of rough in such sizes and quality. Colombian deposits in the Cordillera Oriental were mined as early as in the 1500s but indigenous tribes. The host rocks are rich in vanadium and chromium which give the emerald its lush bluish-green colour, yet the high level of these two elements also causes internal stress in the crystal, resulting in lower clarity of emeralds. Thus emeralds of intense colour and superb clarity are exceedingly hard to find.

    Only a connoisseur can full appreciate the rarity and chances for even one Colombian emerald of superb quality and impressive size to be formed. Not only does it require nature's blessings with the most suitable conditions, but also the technical expertise of a craftsman to turn the rough into a substantial gem. This emerald, endowed with the special qualities from its Colombian provenance, with a respectable size of over 18 carats and a well-proportioned cut, as well as the glorious setting of Graff, is certainly a remarkable jewellery masterpiece.
