What is the gem in this ring?

It shows 18k GE on the band, which is gold plated I beleive. But what is the gem called? Blue Glass?

 

gold electroplate...and glass would be a good guess...

 

That would be my first guess, doubly so since the side stones are glued in.

 

Maybe meant as an approximation of the sapphire engagement ring Charles gave to Diana & William in turn gave to Kate?

I think you gals have got it.......I remember seeing a news report of this ring flooding the market.....

 

The first generation Princess Di copies were the same shape and color as hers, only made out of the proverbial glass and brass. This one is similar, but sapphire and diamond rings like this have been around since at least the Victorian era.
