Look out Frodo, because Rob Kardashian is the new Lord of the Ring!

When the back-in-the-public-eye reality star proposed to his girlfriend of two months Blac Chyna, he really, really opened up his wallet.

According to TMZ, Rob popped the question by dropping $325,000 on the engagement ring. He purchased the ring from Los Angeles-based celebrity jeweler Ben Baller, who is one of Kanye West's favorite jewelers.

Chyna's ring is a 7 carat, round brilliant cut diamond in a diamond eternity band setting. The clarity is VS1, which means that is "very slightly" imperfect and that the trained eye would only be able to see the imperfections when viewed under 10x magnification.

The jeweler posted a close-up video of the stunning sparkler on Instagram.

"Congrats to @RobKardashian & @BlacChyna on getting engaged," he captioned the snap. "Rob, I have never seen you this happy before and I've known you since you were a teenager."

"I'm glad you came to your day 1 homie to get this massive [ring emoji] for your lady. You know I don't play when it comes to diamonds. God bless #7Carats #VVS #IFANDCO #BlacChyna #RobKardashian."

He later took to Twitter to squash all media questions about the big news. "I am not answering any questions about my boys engagement," he wrote. "What's on my IG page is all you get. Congrats Rob and Angela!"

Multiple reports claim Rob popped the question on April 4 and Chyna said yes. To celebrate, the newly betrothed pair appear to have hit up a Los Angeles strip club with Blac Chyna's mom, Tokyo, who reportedly flew out to Los Angeles the previous day to meet her daughter's boyfriend.

An insider told the site, "Tokyo thinks he's 'the one' and is a way better match for her daughter than Tyga ever was. She loves Rob's positive attitude, kindness, good manners and sees he treats Chyna like a queen."

On April 5 Rob posted a photo of his girl's giant new bauble. Chyna, too, posted a photo of her jewelry in a snap with Rob. She simply captioned the photo "YES !…!…!"

YES !...!...!

Later, she shared the jeweler's video of the ring that shows it glistening in the light.

"I'm so blessed and honored to have good man in my life, I love you @robkardashian !," she captioned the video. "#7carats #VVS @benballer."
