GEM DIAMONDS LIMITED

("Gem Diamonds" or "the Company")

2019 Annual Report and Notice of 2020 Annual General Meeting

The Company announces that the 2019 Annual Report (available on the Company's website since 11 March 2020) and the Notice of 2020 Annual General Meeting are being distributed or made available to shareholders electronically today, 30 April 2020.

The Company's Annual General Meeting will be held on Wednesday 3 June 2020 at 10.00 am (BST). Given the need to observe the UK Government's current guidance on social distancing as well as prohibiting all non-essential travel and public gatherings of more than two people, regrettably our AGM will be run as a closed meeting. The AGM will be held at Medlar House, Manor Road, Wantage, Oxfordshire, OX12 8NF, United Kingdom.

The Board will ensure a quorum is present and no additional shareholders will be able to attend the meeting as this would be in contravention of current legal restrictions. The AGM this year will be purely functional and address the formal resolutions detailed in the notice of meeting. We strongly encourage all shareholders who wish to participate in the AGM to appoint 'the Chairman of the meeting' as their proxy and to complete and return a proxy form to ensure all votes are included.

In compliance with Listing Rule 9.6.1, copies of the above documents will be submitted to the UK Listing Authority and will shortly be available for inspection via the FCA National Storage Mechanism

Copies have also been published on the Company's website at www.gemdiamonds.com/investors

The Gem Diamonds Limited LEI number is 213800RC2PGGMZQG8L67.
