London Jewellers Who Sell
Natural Diamonds Only
Some houses have declined lab-grown entirely, on the argument that a mined stone holds its value in a way a manufactured one does not. Whether you agree or not, it is worth knowing before you walk in, because these jewellers will not show you a lab-grown alternative.
It is a small group, and that is the point: most of the trade now sells both, so a house that has held the line on mined stones has done it deliberately. They sit at the traditional end of the market and it shows in the work.
22 verified jewellers are confirmed natural-only, meaning no lab-grown range appears anywhere on their own website. The full set is below. Ranked on the same Wilson score used for the Top 100, which weighs the proportion of positive reviews against how many stand behind it. Full method.
