Ciara's Engagement Ring Outshines Her Racy Birthday Outfit

All eyes were on Ciara's stunning engagement ring last night (Oct. 28) as the singer celebrated her 28th birthday at the Moet Rose Lounge Houston at The Hotel Derek in Texas.

Ciara's 15-carat diamond ring by Avianne & Co. features a large center emerald cut diamond, two slightly smaller side diamonds, as well as diamonds on the band. According to People, it is estimated to be worth just over $500,000.

The "Get Up" singer was rocking a cutout, see-through frock, but her sparkler stole the show as it glittered across the room. And although her new fiancé, rapper Future, was not present for the party, Ciara looked beyond happy as she toasted to the occasion.

"I Had So Much Fun Celebrating BDay and All With Moët in The H-Town!! ❤ Dress: #AlonLivne," she wrote, posting this photo on Instagram:
