Zac Brown may be known for his band’s infectious country hits, but a good cause has him hoping you’ll like his jewelry-designing skills too.

The singer has collaborated on a chain and pendant line with William Henry founder and chief designer Matt Conable, titled William Henry’s JEKYLL + HYDE (named after the Zac Brown Band‘s new album) and benefiting his Camp Southern Ground charity.

“I’m really particular about the jewelry I wear, so I wanted to help create something super masculine and cool,” Brown, 36, tells PEOPLE of his newest venture, which was inspired by a piece of equipment he’s quite familiar with: a guitar-pick holder.

“I’m always losing my picks down in my pocket or they fall out, so now I will always have a few spares hanging around my neck,” says Brown, who designed the chains for the collection. “They turned out really amazing. I’ve been wearing my prototype all week.”

But more important to Brown than the jewelry he helped create is the charity that will benefit from part of the proceeds. “The camp that we’re building is a sleep-away camp for kids of all abilities, so we’ll have children who have developmental disorders mixed in with kids who do not and kids that come from all different kinds of economic situations,” Brown says of Camp Southern Ground. “It’s a $100,000,000 project and it’s basically a big healing university.”

And Brown – who says he was a camper, counselor and staffer in his younger years – hopes the charity will continue to mold young lives just the way camp did for him.

“I’m really excited to provide opportunities to kids,” he says. “To teach a kid and instill some hope in them. Camp was amazing for me and helped shape my life. I want to help teach kids things that they will carry with them for the rest of their lives.”
