Ciara fiance's ex-wife throws shade at their engagement ring...

Russell and ex-wife divorced in 2014 after claims she had an affair with the then-Seahawks wide receiver Golden Tatehas. 

She took to her twitter handle to shade Ciara's engagement ring by choosing an old photo of her, casually showing off her huge 8 carat diamond ring while Ciara's is said to be a 5 carat ring. 

Despite her ring being bigger, Ciara's has more quality, said high-end jeweler, 'David Harris' as he told Hollywood Life about Ciara's ring.

 “This is one incredible ring,”  “This brilliant cut solitaire is approximately 12 to 15 carats and looks to be a D through F colorless diamond, which means it’s a really good diamond.  I would estimate the center stone be worth between $2 and $2.5 million based on one which I recently sold to a very wealthy client.”
