As it turns out, Hayden Panettiere designed her gorgeous engagement ring herself!

The Nashville star gave us the scoop on her sparkler at the Environmental Media Awards Saturday evening, telling E!'s own Marc Malkin and Ali Fedotowsky she created the ring with Montblanc.

"They made me this amazing book where they did a bunch of sketches," Panettiere said. "I told them my idea over time and tweaking things here and there, it came to fruition."

Although the actress couldn't stop gushing over her ring, she kept mum on how her boxer fiancé Wladimir Klitschko popped the question, simply saying the proposal was "romantic."

As we reported earlier in the week, the 6-carat, emerald cut, diamond engagement ring, has an estimated value of about $500,000.

Panettiere officially announced her engagement just a couple of weeks ago during an appearance on Live With Kelly & Michael, after rumors started flying in August she was set to tie the knot when she was spotted with a huge sparkler on her ring finger.

The 24-year-old actress was on hand at the event to receive the EMA Futures Award for her dedication to ecological issues.

The award recognizes younger entertainers for their potential to be environmental activists.
