Ring-a-ding-ding! After getting engaged last month, 19 Kids and Counting star Jessa Duggar showed off her engagement ring in a new video posted via Instagram on Sunday, Sept. 7. 

The fifth eldest Duggar child, 21, offered a glimpse of the sparkler on her ring finger, turning her hand to various angles to show off the ring. My beautiful engagement ring!" she captioned the video. ".75 carat diamond--18 karat gold band. Gorgeous!" 

The princess-cut diamond is set on a unique thin, waved band. Duggar, who is set to wed fiancé Ben Seewald, shot the ring against her seafoam green manicured nails.

Duggar and Seewald got engaged in August after 11 months together. "We are so blessed to be engaged!" the couple said in a statement with the news of their wedding plans. "God has written an amazing story through our courtship, and another chapter has just begun! We are thrilled to see what the future holds — especially the wedding bells!"

It's an exciting time for the expansive Duggar family, as Jessa's older sister Jill recently announced that she is expecting her first child with her new husband Derick Dillard. Jill was the second of the 19 Duggar children to get married, following the oldest son Josh, with Jessa hot on their heels. 

"Y'all! I still can't believe it!" the reality star said earlier after she received her ring. "I'M ENGAGED TO THE MOST AMAZING GUY ON EARTH! Every time I look down at the ring on my finger...it takes my breath away! I love you, @ben_seewald!"
