I'm almost 50, grew up with both my Mum and both S-mum's had real 2+ carat diamonds, me naaa; sorry but if me and they can't tell :mysmilie_11:
but I have had my "diamonte" whatever complemented on; from a BIG fake bought 12 yrs ago and still being worn to a newish QVC one; I now alternate them, the original fake keeps needing re-setting, but then so would a real diamond, and at worst I loose a couple of quid of stone; less than the bit the insurance expect you to pay
One of my school friends is a jeweller, you need a light box to tell the difference :mysmilie_11: sorry I can find better things to spend the money on,
