About the Diamonds
The journey of a diamond can now be documented with detailed precision thanks to the technological and traceability enhancements, from the moment it is discovered in the mine, to the cutting and polishing stages and beyond. When making such a substantial purchase one wants total reassurance, and with this purchase, that is a given. Electronically mapped, diamonds carry detailed records that culminate in their return from the GIA, complete with certification and ready to be set into a timeless piece of jewellery.
Mined in Botswana, this exceptional pair meets the highest standards across every critical criterion by which diamonds are judged. They are certifiably completely flawless, both internally and externally, and have excellent polish and symmetry. D-colour diamonds, these precious stones carry the highest grade for a white diamond. Belonging to the rare subgroup known as Type IIa – representing less than 2% of all gem-quality diamonds – these diamonds are the most chemically pure, often exhibiting extraordinary optical transparency. Free from measurable nitrogen or boron impurities, these diamonds carry the highest thermal conductivity. Accompanied by two GIA reports dated June 24, 2024, these diamonds have been determined to be Type IIa, reaffirming their rarity and provenance.
Provenance
The words "provenance," especially when used in relation to jewellery, or works of art, leads one to think about the individuals who owned or wore it. However, there's another important aspect of provenance: the place of origin. The heritage of the Botswana diamonds is highly valued.
Diamonds are renowned for being the hardest natural substance known to man, a staggering 58 times harder than the second toughest mineral on Earth. The only material capable of scratching a diamond is another diamond. While it is very important to determine the value and pedigree of a diamond, the predominant focus of the industry has mostly been placed on their colour and clarity. However, this reality has shifted in recent years. Driven by consumer demand, significant progress has been made in understanding the provenance of these precious gems.
To uphold the integrity and ethical provenance of its diamonds, ODC – the largest source of guaranteed Botswana diamond production in the market – subjects the gems to rigorous certification processes conducted by third-party organisations. Recently, ODC introduced the Green Star Source Programme, which allows for the traceability of polished diamonds back to their origins in Botswana.
Botswana Natural Diamonds
Today Botswana is the world’s number one diamond-producing country by value, thanks to its impressive reserves of diamonds. The diamond mining in the Southern African country operates under a government licensing agreement, and natural diamonds have long been the cornerstone of Botswana’s economic development contributing 30% of the nation's GDP, with the cutting, polishing, and trading of diamonds adding another 5%
In 2001 the Botswanan government established legislation stating that at least 40% of all revenue generated from diamond exports be reserved for the benefit of future generations. The remaining funds would go towards investments in the country’s infrastructure, education, healthcare, and social security. Botswana's remarkable economic transformation has been largely attributed to the discovery of diamonds, but most importantly, it is the careful management and regulation of these rare and precious stones that has truly fuelled the nation's progress.
The once in a lifetime opportunity to purchase this pair of diamonds through Sotheby’s Hong Kong auction house is a chance to own a piece of history and make a purchase that you know, will last forever, for you to enjoy today and for future generations to enjoy tomorrow.
