Paris Hilton’s monstrous diamond engagement ring is worth about $2 million — but the crazier part is when Chris Zylka knew she was the one, and ordered the rock.
Celeb jeweler Michael Greene, who designed Paris’ multi-million dollar bling, tells TMZ … Chris reached out to place his order 5 to 6 months ago, back in the summer.
Paris and Chris had just gone public with their relationship back in February, so it was likely less than a year into things that he decided he wanted to lock down Paris.
Greene also tells us the huge diamond — 20 carats strong — took about 4 months to cut, and the setting only took a couple days. He says Chris came in to get it right before their Aspen Ski trip .
