Why is the DNL stone so cloudy? Usually is takes a CZ some dirt and a lot of wearing to cloud up like that, you sure you didn't wear it for 6 months before taking those pics??
Taking into consideration that DNL advertises it's product as a "perfect man-made diamond" and claims that it will never fade, even though all they're selling is cheap CZ, I don't think it matters anyway. If DNL's stones lived up to their hype, they'd NEVER look like that anyway.
An Asha certainly wouldn't look like that after 6 months of wear.
