British songstress Rita Ora had secretly tied the knot with Academy Award-winning director Taika Waititi last summer, but saved the big reveal of her emerald engagement ring for her appearance on Wednesday night's edition of The Tonight Show with Jimmy Fallon.

Ora said, “I haven’t actually shown anyone my ring," but then explained that the reason she was about to unveil the jewelry on The Tonight Show was because she "loves" Fallon and feels he's a big part of her and her fiancé's relationship because they watch him every night.

After extending her hand to give Fallon a quick peek at the sizable emerald set in a pavé diamond halo, she turned her hand vertically and aimed her ring straight at the camera so the viewers at home could get closeup look at the sparkler. The “I Will Never Let You Down” singer, 32, paired her new engagement ring with a delicate pavé diamond wedding band.

“Ooh-la-la,” Fallon said. “That’s gorgeous!"

"He did good," she responded.

When asked to share the story behind how Waititi, 47, selected the ring, Ora sheepishly admitted that she controlled the lion's share of the decision.

"Well, I may have, you know, guided him," she confessed. "When you know what you want, and I felt like I really knew I wanted to be with this person, I just wanted it to feel really right, and so I may have taken him to the shop and I may have pointed out exactly what ring I wanted!"

Two UK-based jewelers interviewed by Page Six Style put the ring's value at somewhere between $400,000 to $500,000 and estimated the weight of the emerald to be in the range of 8 to 10 carats.

Among the A-listers who received emerald engagement rings are Zoe Saldana, Megan Fox, Halle Berry, Victoria Beckham and Jaqueline Kennedy Onassis.

Ora, who is currently a judge on the British version of The Masked Singer, told Fallon that her latest single, “You Only Love Me,” was the result of a surge of creative energy sparked by her new relationship.

"My life has changed so drastically," she said. "Making a decision to spend the rest of your life with someone is a big decision. It got me writing again and I just really got inspired by love."
