He put a ring on it — and it's a big one! Fitness goddess-turned-celebrity Kayla Itsines announced her engagement to longtime beau, Tobi Pearce, and we can't stop staring at her ring! The 26-year-old took to Instagram last week to reveal the exciting news, and now many BBG fans are dying to know all the deets about the giant sparkler adorning her left hand.

"Kayla's ring features what appears to be a cushion cut diamond of approximately three carats," Kathryn Money, VP of Strategy and Merchandising at Brilliant Earth told Life & Style exclusively. "This sparkling stunner is timeless and feminine, featuring a delicate diamond halo and diamond adorned band set in 18 karat white gold or platinum."

Although the ring isn't from Brilliant Earth's (seriously stunning) collection of gems, Kathryn did drop some shocking stats about the diamond in her expert opinion. "Our estimated cost of the ring is between $40,000-60,000, depending on the quality and specific characteristics of the diamond." NBD!

Back in 2015, Kayla gushed about her man on Facebook. "A little about my boyfriend Tobi. In Tobi's profile it says 'expelled from school'. People always think this is a bad thing," she wrote in the lengthy caption. "Tobi was actually asked to leave school because he spent a lot of his time being bored and yes this made him be a little distracting to others. He's a genius. I'm not saying that because I think he's smart, he really is a genius with an AMAZING mind."

So amazing, in fact, that his education level was equivalent to that of a college student when he was just a young teenager. "He was studying classical piano from aged four, and was at university level by 13 years old," she continued. "He is able to work out mathematical problems in a matter of seconds. He has a photographic memory. He can analyze a person or situation and know EVERYTHING that is going to happen next. He can finish your sentences (haha sometimes this is annoying). He can fix anything, learn new languages in a few months, NOTHING is too difficult for him and as amazing as this sounds… He thinks it's a burden at times. He is the most amazing person you have ever met. He sometimes comes across as arrogant because he already knows what you are going to say, so he is quick to respond. But when you get to know him, he's the best person you have ever met and can help you succeed or improve yourself in many ways. All you have to do is ask and listen." So sweet!

Unfortunately, your man may not be able to spend his entire salary on a piece of jewelry, which is why BE's lookalike rings Waverly, Odessa, and Fancy Halo will cure your #FOMO. Now if only someone could tell us how to get that body of hers just as easily!
