Is this Toke Makinwa's engagement ring? 

Has Toke Makinwa finally showed off her engagement ring? I'm assuming that's her engagement ring - what else can it be? She's engaged to long time boyfriend Maje Ayida. Pics taken at the Lipton Tea Party which held at Landmark Events Centre, Oniru, Lagos on Friday, Nov. 8th.
