PEACE PARKS FOUNDATION

A portion of the Proceeds will Benefit the Peace Parks Foundation, specifically the Kavango Zambezi (KAZA) project.

KAZA, the Kavango Zambezi Transfrontier Conservation Area, is the world’s largest land-based transboundary conservation area. Covering about 520,000 km² across Angola, Botswana, Namibia, Zambia and Zimbabwe, it links iconic places such as Victoria Falls and the Okavango Delta into one shared landscape for wildlife and people.

KAZA is home to around three million people and the world’s largest population of savanna elephants, estimated at about 228,000 animals. It also supports globally important populations of wild dogs, lions and cheetahs, as well as more than 650 bird species. 

The vision is simple: nature does not stop at borders, so conservation cannot stop there either. KAZA helps keep wildlife routes open, protects rivers and habitats, supports tourism, and creates opportunities for communities living alongside wildlife.

Peace Parks Foundation has supported KAZA since its early development, helping the five partner countries move from feasibility studies to the Treaty that formally established the landscape in 2011. Today, Peace Parks continues to support cross-border collaboration, tourism development, wildlife corridors and community-led conservation areas such as Simalaha Community Conservancy and Sioma Ngwezi National Park in Zambia, helping to protect one of the last great connected wildlife landscapes on Earth while supporting the communities who call it home. 

At its heart, KAZA is about connection between countries, between wild places, and between conservation and the people whose lives depend on healthy landscapes.

Diamonds are miracles of nature. Their creation requires a complex chain of geological conditions, yet the result is exquisitely simple: a dazzling crystal of pure carbon. A diamond’s rarity, unmatched hardness and brilliance have made it an enduring symbol of purity, strength and prestige across civilizations for thousands of years.

Long before their origins were fully understood, diamonds were revered for what were perceived to be their mystical and divine properties. In India, the oldest known source for diamonds, warriors and spiritual leaders prized them as indestructible amulets, protecting against evil spirits and harm. In the Diamond Sutra, one of the most influential Buddhist texts, the stone represents supreme wisdom and clarity, cutting through illusion to achieve a full awakening of mind and spirit. The Ancient Greeks and Romans believed diamonds to be fragments of fallen stars or the tears of the gods, and Cupid’s bow was said to be diamond-tipped, able to pierce the most hardened of hearts. Centuries later, the Silk Road and Venetian trade routes brought diamonds to Europe where they became symbols of wealth and power. While no longer thought to fall from the heavens, diamonds’ rarity and beauty continue to inspire.

A diamond jewel is a collaboration between nature and craftsman. Each diamond rough is transformed through thoughtful cutting and polishing to tease out its full potential. The cutter analyzes the rough and determines what it shall become: a round brilliant to maximize light return and fire? A step cut to showcase the purity of the material? Or, perhaps, an old mine cut, a style developed centuries ago and most often found in antique jewels, from tiaras to rivières. The cut is distinguished by its cushion-shaped outline, broad facets and open culet, all of which lend the stone a distinct character and charm. Famous old mine-cut diamonds include the Hope, the Tiffany Yellow and the Grand Mazarin. The scarcity of diamonds has led many of these stones, particularly larger specimens, to be recut in order to align with modern specifications. Recently, there has been a renewed appreciation for old mine cuts, both for their beauty and their association with the grandeur of yesteryear.

The exquisite elongated old mine-cut diamond offered as lot 34 represents the continuation of a partnership between De Beers and Sotheby’s that celebrates diamonds as cultural icons and works of art. In addition to its cut, the diamond’s Type IIa classification brings to mind the legendary diamonds of Golconda, admired for their exceptional optical transparency. In April, Sotheby’s Hong Kong offered the Jwaneng 28.88, a spectacular modern round brilliant with excellent polish and symmetry. This was followed by a pair of perfectly matched 18.38-carat round diamonds at Sotheby’s Geneva this May, also with excellent polish and symmetry. All three diamonds were cut with extraordinary precision in accordance with Marcel Tolkowsky’s ground-breaking prescription for the modern round brilliant cut developed in 1919. Lot 34, however, was carefully faceted in an intentionally non-formulaic manner to reflect the human touch and to lend the stone its unique, captivating character.
