The talented songstress, who got engaged to her rapper boyfriend Future over the weekend, flashed the sparkler just days after the proposal.
It seems as if Future had a similar idea to Kanye West on how to pop the question, as both men chose their fiancée's birthdays to propose. The Yeezus rapper recently asked his long-term girlfriend Kim Kardashian to be his wife on her 33rd birthday.
Ciara and Kim have flaunted their lavish engagement rings in public, and both are stunning 15-carat rocks from Avianne & Co. and Lorraine Schwartz respectively.
Ciara's sparkler also bears a striking resemblance to Kim's previous engagement ring, when Kris Humphries proposed to the queen of reality TV in 2011.
Ciara's eye-catching rock, which was designed by Future, features emerald diamonds flanked by more diamonds around the side.
"The ring is a very intricate design which took longer to actually design than it did to produce," an insider told PEOPLE.
"We went through several moulds and concept models before landing on the proper design, which allowed for maximum shine and stability in the diamonds. This vision of blending ring styles together allowed for a very unique ring."
Kim's engagement ring from Kris, meanwhile, featured a 16.21-carat centre diamond and two 1.8-carat side diamonds. The ring was said to be worth $2million, but sold for a total of $749,000 at a Christie's auction in New York City earlier this month.
The shape and design of the ring also echoes Angelina Jolie's engagement ring from Brad Pitt. The oblong-shaped rock is inset into a thick band, and reportedly took the Hollywood hunk a year to design.
Emerald cut rings are popular with many celebrities, with the likes of Grace Kelly, Beyoncé, Kate Hudson, Victoria Beckham and Reese Witherspoon all wearing the style.
