Diamonds are forever! Demi Lovato and Max Ehrich split just two months after getting engaged in July 2020, but her massive engagement ring will forever be one of the most impressive sparklers we’ve ever seen.

“Demi’s showstopping engagement ring features what appears to be an estimated 8 to 10-carat emerald cut diamond set on a platinum or white gold band,” ring expert Kathryn Money, Brilliant Earth‘s SVP of Merchandising & Retail Expansion, told Life & Style shortly after Max popped the question. “The center diamond is framed by beautiful trapezoid shaped accent diamonds estimated at ¾ carats each, for a total carat weight of the ring of 9.5-11.5 carats.”

Because of these factors, the ring is estimated to be worth between $450,000 and $850,000.

According to the ring expert, emerald cut engagement rings have been surging in popularity lately. In fact, the shape has been worn by happily engaged celeb babes like Jennifer Lopez, Nikki Bella and Jennifer Lawrence.

“Many opt for elongated diamonds – including emeralds, elongated cushions and ovals – as their shape offers a flattering look, lengthening the wearer’s finger,” Kathryn explained further. “As we see delicate settings trending, the thicker band gives Demi’s ring a traditional, timeless touch.”

Demi, 28, and Max, 29, announced they were taking their relationship to the next level on Instagram on July 22. “When I was a little girl, my birth dad always called me his ‘little partner’ – something that might’ve sounded strange without his southern cowboy-like accent. To me, it made perfect sense,” she wrote. “And today that word makes perfect sense again, but today I’m officially going to be someone else’s partner.”

She then turned her attention to the actor. “I knew I loved you the moment I met you. It was something I can’t describe to anyone who hasn’t experienced it firsthand, but, luckily, you did, too. I’ve never felt so unconditionally loved by someone in my life (other than my parents), flaws and all,” she gushed in her post. “You never pressure me to be anything other than myself. And you make me want to be the best version of myself. I’m honored to accept your hand in marriage. I love you more than a caption could express, but I’m ecstatic to start a family and life with you. I love you forever, my baby. My partner. Here’s to our future!!!!”

Sadly, Life & Style confirmed on September 24 the two ended things for good after first sparking romance rumors in March. They went public with their relationship in Justin Bieber and Ariana Grande‘s “Stuck With U” music video shortly after, but it looks like they were not meant to be.

Despite their romance not working out, we’ll *never* forget Demi’s engagement ring.
