MOH London

MOH London represents the new generation of Hatton Garden. Their entire model is built around technology and transparency — a ring builder tool with access to over 1,000,000 GIA and IGI certified diamonds, with prices shown upfront before any conversation. That is not a typo. MOH London lists over one million certified stones, which is significantly larger than any other Hatton Garden jeweller's searchable inventory.

Their natural diamond collection is GIA certified — the Gemological Institute of America, widely regarded as the most respected diamond grading laboratory in the world. Their lab-grown stones carry IGI certification to the same standard. Both categories are searchable through the same ring builder tools with the same upfront pricing.

The consultation experience is different from a traditional jeweller. You arrive having already designed your ring online, selected your diamond, and seen the price. The in-person appointment is confirmation — viewing the stone, checking the setting, making any final adjustments. It is the opposite of the old model where you walk in blind and a salesperson steers you.

MOH also offers matched diamond pairs for earrings — a searchable category that most Hatton Garden jewellers do not provide. If you are buying diamond studs or drop earrings, you can search for pairs matched on cut, colour, clarity, and carat weight, rather than relying on a jeweller to hand-pick a pair from whatever they have in stock.
