‘Two and a Half Men’ Star Aly Michalka Shows Off Vintage-Style Engagement Ring

Two and a Half Men star Aly Michalka took to Instagram and Twitter last week to announce her engagement and show off her brand new — and classically beautiful — vintage-style ring from director boyfriend Stephen Ringer.

Simon G Jewelry CEO Zaven Ghanimian told Eonline.com that he believes Michalka’s princess-cut center stone is set in platinum and weighs 2 to 3.5 carats. He estimated the ring's value to be in the range of $20,000 and $30,000. The princess cut is the second-most-popular diamond shape for brides, trailing only the round brilliant.

In announcing her engagement on Instagram, Michalka had a little fun with her 182,155 followers. First she posted a pic of her and her younger sister AJ with the caption, “Hmmm....no one's noticed yet. #Lookcloser”. A careful inspection of the photo reveals an engagement ring on Michalka’s left ring finger.

Later the same day, 25-year-old Michalka posted a crystal clear closeup of her left hand with this caption: “So this happened…7/8.”

On Facebook, she wrote, "Wanted to share the exciting news! Feel very blessed to know such a great love #engaged x Aly"

Michalka, who launched her acting career with roles in the Disney Channel's Phil of the Future and CW’s Hellcats, recently earned a recurring role as Brooke in Two and a Half Men. She and AJ are also in a band called 78Violet.

One day after announcing her engagement, Michalka was back on Instagram with a romantic closeup photo of her and her beau. She captioned the photo, “So proud to be your girl.” The couple had been dating for a little more than a year and a half. They have yet to announce a wedding date.
