Diamonds Natural & Lab Grown
With over 15 years of international diamond trading expertise, we offer the world's finest natural diamonds alongside exceptional lab grown stones — both certified, conflict-free and set by our master craftsmen in Hatton Garden.
Formed by the Earth,
Over Billions of Years.
Natural diamonds are nature's rarest miracles — formed deep within the Earth's mantle under extreme heat and pressure over billions of years. Each one is entirely unique, carrying its own individual character that no two stones share.
Same Diamond.
Grown with Science.
Lab grown diamonds are chemically, physically and optically identical to natural diamonds — the only difference is their origin. Created in controlled laboratory environments, they offer the same breathtaking brilliance at a fraction of the cost.
Understanding The 4Cs
The most important of the 4Cs. A diamond's cut determines how brilliantly it reflects light. We source only Excellent and Ideal cut stones for maximum fire and sparkle.
Diamonds are graded D (colourless) to Z (light yellow). We recommend D–H for the purest near-colourless brilliance, with D–F being the most prized and rare.
Clarity refers to internal inclusions and surface blemishes. We recommend VS1–SI1 for the perfect balance of purity and value — clean to the naked eye with exceptional beauty.
Carat is the unit of weight for diamonds. One carat equals 0.2 grams. Our collection spans a wide range of carat weights, with bespoke stones sourced to any specification.
Earth-Born Diamond Jewellery
Each piece is set with a GIA or IGI certified natural diamond — conflict-free, ethically sourced and hand selected by our experts for exceptional cut, colour and clarity.
The Same Diamond. A Different Origin.
Lab grown diamonds are created using HPHT (High Pressure High Temperature) or CVD (Chemical Vapour Deposition) processes — replicating the exact conditions found deep in the Earth's mantle.
Even gemologists cannot distinguish a lab grown diamond from a natural one with the naked eye. Both are pure carbon crystal — only specialist equipment can tell them apart.
Every lab grown diamond we use comes with IGI or GIA certification — graded on the same 4C standards (cut, colour, clarity, carat) as natural stones, with full documentation.
Lab Grown Diamond Jewellery
The same brilliance. The same certification. A more accessible price point. Our lab grown diamond collection offers exceptional stones, ethically grown and set by hand in our Hatton Garden atelier.
