Dianna Agron is engaged to musician Winston Marshall. Though the couple has been engaged for some time now, the actress and singer gave fans a glimpse of her gorgeous new rock. The former “Glee” star showed off her diamond engagement ring while attending the Erdem show at London Fashion Week Monday. 

Mumford and Sons’ Marshall, 27, reportedly popped the question to his lady love during the holidays. Dianna looked stunning in a blue and white floral patterned dress by Erdem. The sleeveless feminine dress featured a halter neck and flared skirt with an asymmetrical detailing near the waistline.

The actress styled her blonde locks into a messy, low ponytail and wore fresh-faced make-up. Agron showed off her huge rock while sitting front row during the Erdem Autumn/Winter 2016 presentation along with Alexa Chung and Daisy Lowe. All eyes were on her ring that is believed to be around four to six carats rose-cut diamond set in a simple yellow gold band.

The ring speaks volumes of Agron’s style and is classic with the complete focus on the rock. Gold seems to be back in fashion with celebrities opting for unique vintage cuts. However, the actress’s diamond ring with a bezel setting is not as popular as other styles but is a definitely a more unique one.

According to VP marketing of Ritani, Mark Keeney, while it is hard to determine the quality of the diamond, the ring would be around the $100,000 range. The very private couple is yet to confirm the engagement but the two are said to be happy together.

Agron and Marshall were first spotted together walking hand in hand in Paris in July 2015. They have also made some appearances together and in August, the pair gushed over each other at the “She’s Funny That Way” premiere after party at Sunset Tower in West Hollywood. This apart, the couple have always kept out of the media glare.
