De Beers Champions Rare Diamond Cabochons In New Vibrations Collection
By Adapting An Ancient, Facet-Free Cutting Technique, The Luxury Jeweler Accepts A 0.5% Yield To Drive Premium Product Differentiation In High Jewelry.
De Beers London has adapted a rare, smooth diamond cut called a cabochon—which has no flat facets—to shape diamonds that look like smooth water droplets. The diamond cabochons appear in Vibrations, a high jewellery collection inspired by “the quiet yet enduring power of inland water” found in De Beers’ key diamond sources of Botswana, South Africa, Canada and Namibia. The collection launch coincided with London Fashion Week.
Unlike traditional diamonds that sparkle through sharp, angled facets, these smooth stones reflect light softly, giving off a deep, luminous glow. However, because there are no facets to hide internal flaws (inclusions), the diamond’s clarity is completely exposed. Without facets to distract from or obscure the diamonds’ internal characteristics, the cabochon technique requires diamonds with high levels of purity and an appropriate crystal structure. De Beers said fewer than 0.5% of diamonds satisfy the necessary colour and clarity criteria, with fewer still possessing the required symmetry and structural quality.
Key Takeaways for Business Students:
- Product Innovation & Heritage: De Beers didn’t invent the cabochon cut—a style traditionally used for colored gems like sapphires and emeralds—nor is it the first to apply it to diamonds. Instead, they adapted an established, rarely used technique to create a unique signature profile.
- Operational & Technical Challenges: Diamond is extremely hard, making facet-free precision shaping difficult. Furthermore, removing facets removes the visual “camouflage” for internal flaws, setting an exceptionally high quality bar for raw material sourcing.
- Market Positioning: De Beers is using this process innovation to drive high-end product differentiation, launching the new stones as part of its exclusive Vibrations high-jewelry collection (specifically featured in the Undulation suite).

Botswana Looks Beyond Rough Diamond Sales, Eyes U.S. Jewelry Market
The Duty Exemption By US Presents An Opportunity For Domestic Jewelry Manufacturers In Gaborone To Bypass Traditional Middle-Market Hubs and Establish A Direct Pipeline To American Consumers
Grappling with a painful downturn in global rough-diamond demand, Botswana is pivoting its economic strategy: expanding up the supply chain directly into American retail shelves while leveraging its resource wealth to fund conservation and diversification.
Speaking on the sidelines of New York Climate Week, Bogolo Joy Kenewendo, Botswana’s Minister of Minerals and Energy, highlighted the southern African nation’s plan to capitalize on a 0% import-tariff rate to the U.S. market. The duty exemption presents an opportunity for domestic jewelry manufacturers in Gaborone to bypass traditional middle-market hubs and establish a direct pipeline to American consumers.
shift The push into value-added manufacturing comes as the world’s top diamond producer by value navigates a broader structural Diamond revenues have long formed the bedrock of Botswana’s post-independence balance sheet, underwriting universal secondary education and tuition-free university funding. However, recent market volatility has underscored the vulnerabilities of a mono-sectoral economy.
Under the Botswana Economic Transformation Programme (BETP)—an initiative spearheaded directly by President Duma Boko and his vice president—the government is directing resources toward manufacturing, agriculture, and broader mining sectors to reduce its heavy reliance on rough diamond sales.
To support its luxury exports, Botswana is recalibrating its brand narrative around origin, environmental stewardship, and social impact. The country recently announced a five-year extension of the “Okavango Eternal” partnership alongside De Beers Group and the National Geographic Society. The initiative aims to protect the ecological integrity of the Okavango River Basin while tying diamond purchases to conservation efforts.
With De Beers currently facing an impending ownership change, officials remain optimistic that any capital restructuring could bring additional funds into Botswana to accelerate its domestic economic transition.
