Ash's sapphire ring almost same as Kate Middleton's

Hey guys!

I noticed this a while back and decided to post it. Aishwarya always has a blue sapphire ring on (I noticed it because my friend has a similar one too; hers is sapphire in white gold). Recently, Kate Middleton got engaged and Prince William gave her Princess Diana's old ring; and it's very similar to the one Ash wears.

Before a war breaks loose on PV, Ash didn't copy it from Kate Middleton; I've seen her wearing it for years now.
