BSR Global: Leading the Diamond Industry into a Digital Future
BSR Global, with over 15 years of expertise in the rough diamond export industry, has established itself as a pioneer in secure and ethical diamond logistics.
Key features of BSR Global’s secure logistics platform include:
In-country teams staffed by ex-British Special Forces for end-to-end protection.
Dedicated Gemologists and logistics managers, supported by an extensive African supplier network.
A cutting-edge gemology lab in New York’s World Diamond Tower (Building 580, 5th Avenue) with four specialized inspection stations.
Lloyd’s of London insurance, secured only after exhaustive due diligence on all business aspects—making BSR one of just two organizations worldwide with Lloyds insurance.
This infrastructure underpins the creation of KimberLite Token, born from the need to overcome traditional banking delays and high costs for multimillion-dollar transfers, persistent provenance issues despite the Kimberley Process, and barriers to investor entry in the exclusive diamond market.
The common ownership by Ian Lavender, a seasoned commodities expert, bridges BSR Global and KimberLite Token, guaranteeing supply chain reliability through seamless integration of physical expertise and blockchain innovation.
Sorting and Grading: Building Trust in Every eDiamond
Our sister company BSR Global deploys a dedicated team of experts directly in-country to meticulously inspect and verify every rough diamond before export. This hands-on approach ensures transparency and quality at every step.
A key part of this process is the detailed examination by a qualified Gemologist, who sorts and grades the stones using time-tested methods suited to the rough diamond trade.
The sorting and grading begins with separating diamonds by size—smaller ones pass through calibrated sieves, while larger stones are weighed precisely on scales. Next, the gemologist classifies each stone by shape, such as the classic octahedral form or irregular macles, to predict how well it might yield polished gems.
Color is assessed under controlled lighting to note any hues from colorless to fancy shades, and clarity is checked under magnification for internal inclusions or surface features that could affect value.
As part of this evaluation, the stones are exposed to ultraviolet (UV) light to observe fluorescence—a natural glow that reveals subtle traits like strain patterns or potential treatments, helping confirm authenticity and refine the grade without invasive testing.
In addition to sorting and grading, the team secures the essential Kimberley Process Certificate (KPC) and obtains export approval from local authorities. This rigorous documentation guarantees that every eDiamond is sourced and exported ethically, giving investors peace of mind in a complex market.

Curated High-Quality Rough Diamonds
We source only the highest-quality rough diamonds from our sister company, BSR Global, to craft our eDiamonds. These are industry-recognized 'Gem-Grade' stones, chosen for their exceptional clarity and potential.
Gem-grade rough diamonds stand out as the top choice for turning raw stones into stunning polished gems ready for fine jewelry. These diamonds are carefully picked for their strong promise of high-quality results after cutting and polishing.
Key Characteristics
Clarity Potential: These diamonds are chosen for having few inclusions—tiny natural flaws—that will not affect the beauty of the finished stone. Typical grades range from VVS1 (Very, Very Slightly Included 1, where flaws are nearly invisible under 10x magnification) and VVS2, to VS1 and VS2 (Very Slightly Included, with minor flaws visible only if you look closely).
Color Range: They feature near-colorless to fully colorless tones, graded from D (colorless) to H (near-colorless). This range boosts their appeal and market value without the extra cost of rare fancy colors.
Size Threshold: For investors, gem-grade rough diamonds usually weigh 5 carats up to 30+ carats. This ensures enough material remains after cutting to create a meaningful polished gem.
When available, our KimberLite eDiamonds also feature sought-after Fancy Colored stones and Flawless gems. These premium selections are offered exclusively through the Auction section of KimberMarket, where verified buyers can compete for some of the world's most coveted diamonds.
Comparing Lab-Grown and Natural Rough Diamonds
Lab-grown diamonds, produced using methods like High-Pressure High-Temperature (HPHT) or Chemical Vapor Deposition (CVD), have reshaped the diamond world by providing cost-effective options for everyday jewelry.
In 2023, they made up about 14.3% of the global diamond supply, totaling around 16 million carats. Yet, more than 90% of these stones are small—typically between 0.5 and 3 carats—ideal for cheap engagement rings and fashion pieces, thanks to efficient production processes.
Scaling up to larger sizes demands far more time and energy, which is why lab-grown diamonds over 10 carats remain rare and expensive to create.
Gem grade rough diamonds of 5+ carats stand as symbols of timeless beauty and rarity, untouched by the rise of lab-grown diamonds. While lab-grown stones excel in accessibility and affordability for smaller sizes, they complement rather than compete with the exclusive world of large natural gems.
