Demi Lovato is celebrating her engagement to boyfriend Max Ehrich by sharing photos of her stunning diamond ring.

On Thursday, the musician announced her engagement via Instagram, where she shared photos of herself and Ehrich embracing on the beach. She also shared some close-up shots of her engagement ring, which features a large, rectangular diamond and two smaller stones on each side.

According to Ajay Anand, the founder and CEO of diamond search engine Rare Carat, the engagement ring could have cost at least $1 million.

In an email to Insider, Anand said the ring featured a 10-carat emerald-cut stone "that does not hide its flaws."

According to the Rare Carat founder, the stone likely has a "very high color and clarity" and could "be a D-color Flawless clarity diamond." That means the stone would have no visible blemishes under 10x magnification and "would sell for no less than $1 million." He added that the diamond was surrounded by trapezoid side stones "for an art-deco look."

Of course, Lovato isn't the first celebrity to wear such an engagement ring. According to Anand, Grace Kelly and Elizabeth Taylor also had large emerald-cut rings. Similarly, Beyoncé and Jennifer Lopez also have engagement rings with "huge center stones that are also emeralds in this size ballpark," according to the CEO.

Lovato and Ehrich announced their engagement on Thursday after quarantining together throughout the pandemic. The couple began dating around the start of 2020.

"I knew I loved you the moment I met you," Lovato wrote to Ehrich on Instagram. "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."

"You never pressure me to be anything other than myself," she continued. "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!!!!"
