H Samuel owner Signet Jewelers is to donate $1 million to the Red Cross Ukraine humanitarian relief efforts through its Signet Love Inspires Foundation.
The group, whose other retail banners include the likes of Ernest Jones and Zales, has already suspended business interaction with Russian-owned entities at the beginning of the invasion.
Signet said the funds will help provide much needed food, medical supplies, shelter and ongoing crisis relief in the country.
To maximise individual giving, the foundation will also match donations from Signet team members by 2:1 up to $1,000 per person per year.
