And when the duo joined the rest of the squad and went under the clippers and shaved their heads in support of Velindre, the diamond specialist in the city also dug deep to boost the campaign.
Kelvin James, Director at the Diamond Centre Wales, recently visited the region's training ground at The Vale and after watching training was on hand to donate £500 to each player to help increase funds.
"We've really enjoyed showing our support for Blues once again this season by sponsoring Kristian and Chris," said Kelvin James. "It's great to see the whole squad getting behind the Velindre fundraising campaign in such a visual way and I was delighted to join the squad at training and be able to pass on the donations to our players."
