Guernsey museum series: Guernsey Diamond Museum

For ladies who profess that diamonds are their best friends, then a visit to the Guernsey Diamond Museum, located at Ray & Scott Ltd, is a sparkly educational experience.

The museum is the brainchild of owner, Martin Search, who wanted to convey to his clients how serious he is about his profession and the diamond industry in general. It’s a unique situation for a jewellery store to devote valuable retail space to a museum, which not only affirms Martin’s passion for his trade, but is now accredited as the only diamond museum in the British Isles.

Discreetly situated at the back of Guernsey’s pre-eminent jewellery store, the museum is located in what was originally the vault for the NatWest bank that formerly occupied the building in the 1930’s.


Featuring an estimated three-tonne door, which according to the original John Tann’s signage on it is “anti-explosive and anti-blow pipe”, the vault door is opened (and secured) by an impressive spindle wheel handle.

The ambience of the museum is immediately created once you enter via this imposing vault door.

The museum’s showcases display:

  • History and Famous Diamonds
  • Cutting, Retailing and Marketing
  • Industrial Uses, Synthetics and Simulants
  • Diamond Origin and Structure
  • Mining, Sorting and Grading
  • Examples of estate jewellery from the 1930s.

Learn about the crucial 4 C’s to choosing a diamond – cut, colour, clarity and carat weight.

Gasp in awe at the replicas of the world’s most famous diamonds, from the most famous Second Star of Africa (or Culliman II) at a massive 317 cts to the Piggott at 49.04 cts.

There is also a ‘must view’ 20-minute DVD highlighting the complexities of the diamond mining industry.

Martin and his team welcome the opportunity to host private parties for local corporations/banks and accountancy companies, visits by clubs and associations, including youth groups. Private corporate parties are invited to bring along their clients to enjoy presentations about diamonds and jewellery while enjoying a glass of champagne.
