The house · Hatton Garden, London
A bench,
not a window
Yasmin Diamonds is a Hatton Garden workshop with a showroom attached, rather than a shop that sends its work out. What we sell, we can also size, set, repair and value — and the people who do that are upstairs.
Who we are
The short version
We deal in fine jewellery and rare timepieces, and we make and finish a great deal of what we sell. Stones are bought on certificate and checked again in the hand. Metal is hallmarked at the London Assay Office before anything reaches a customer.
The trade in Hatton Garden, London runs on reputation held over decades, and the whole of this site is built on that footing: a price you are quoted is a price that can be explained, and a piece you are shown is a piece we can account for.
