ONE VISION. ONE VALUE CHAIN.
ONE GEMS brings the activities previously presented under Simba Jewellery into a clearer, stronger and more credible business platform within ONE 8 Group.
Our ambition is to create value at every stage, from geological knowledge and responsible sourcing to cutting, certification, design, finished jewellery and international distribution.
THE ONE GEMS PLATFORM
A disciplined platform designed to connect physical resources, technical expertise, responsible operations and commercial demand.
Geological review, field evaluation, sampling and independent technical verification.
Responsible extraction planning with safety, traceability and local participation at the centre.
Sorting, cutting, polishing, grading and certification to unlock the stone's true potential.
Distinctive jewellery and gemstone collections designed for selected consumer and trade markets.
International buyers, strategic partners, private clients and transparent market channels.
ROOTED IN KENYA
Kenya is internationally associated with coloured gemstones, including tsavorite, ruby, sapphire, garnet, tourmaline, aquamarine and other gem varieties.
The original Simba Jewellery materials describe historical prospecting activity and mineral potential in north western Kenya. ONE GEMS will present any licence, reserve, valuation or geological claim only after current legal and independent technical verification.
Credibility first. Documentation, due diligence and regulatory compliance before promotion.
FROM THE FIELD
Documentary photographs from mining, recovery and preliminary sorting activities, presented as operational evidence rather than studio imagery.


















Original footage from the mining area
Images and videos document field activity and rough material. Gemstone identity, grade, treatment and commercial value require qualified independent testing and certification.
