Draymond Green spared no expense when he proposed to his girlfriend last month -- TMZ Sports has learned the ring he used to pop the question is worth $300,000!!!
Remember, Warriors coach Steve Kerr accidentally broke the news a few weeks ago that Green got engaged to actress and "Basketball Wives" regular Hazel Renee ... but now, we've got deets.
There was a helicopter. There was a yacht. Oh yeah, and a big ass ring.
Turns out, Day Day hit up Jason of Beverly Hills for the 6-carat flawless diamond ring .
