NAJ renews TH March as preferred insurance partner for jewellers

For jewellers holding diamonds, gold and finished stock worth more than a season’s sales, the renewal of TH March as the National Association of Jewellers’ preferred insurance partner is less a ceremonial nod than a reminder that cover and crime prevention now sit side by side.

The National Association of Jewellers announced on 11 May 2026 that it would continue its relationship with TH March, a partnership it said spans 120 years. NAJ chief executive Ben Massey described TH March as a long-standing supporter of members and the wider jewellery trade, while TH March managing director Simon Dawe said the broker remained focused on specialist insurance solutions, guidance and support that help businesses maintain and grow. For a sector exposed to theft, robbery and other security threats, that language matters because standard commercial insurance rarely matches the realities of high-value jewellery stock, transit and display.

TH March said it has served the jewellery trade since 1887 and positions itself as the UK’s most experienced jewellery trade insurance broker. It also works with the Company of Master Jewellers, the National Pawnbrokers Association and the British Pearl Association, putting it among the main specialist brokers active around the trade. The NAJ partnership also gives members access to the TH March Club, an exclusive benefits programme for the sector.

The deeper value of the renewal sits in SaferGems, the anti-crime initiative that links insurance with security intelligence. Launched in June 2009 after concern about rising crime against the jewellery industry, SaferGems is approved by the Home Office, endorsed by the National Police Chiefs Council and hosted by the British Security Industry Association. It is funded by the retail jewellery industry through TH March and the NAJ, and the association says it has direct access to police intelligence and has sent out more than 2,500 alerts in 10 years.

That makes the partnership a practical warning as much as a commercial arrangement. Jewellers reviewing their own policies should check whether stock values are still aligned with today’s inventory, whether alarm and storage requirements reflect current crime patterns, and whether claims procedures are strong enough to handle a major loss without delay. They should also look closely at transit cover, premises security and how quickly they receive and act on crime alerts.

The signal from the trade is clear: specialist insurance is no longer just about paying claims after a burglary. In an era of rising exposure and tightly coordinated criminal activity, the best policies now depend on intelligence, prevention and a broker that understands how the jewellery trade really works.
