Having been "caught" by other shopping channels in the past with diamond rings that appear to be a reasonable price, I now realise that any diamonds that look cloudy with little sparkle on screen, generally are in real life.
Having been very fortunate in having a very expensive diamond ring bought for me, the comparison between this and the cheaper versions I purchased from shopping channels is staggering. A carat of diamonds sounds a lot, but you would be better off spending your money on a decent Morganite or equivalent as it will have more sparkle than the cloudy diamonds ever will.
