I absolutely love this engagement ring! I cannot say how much I love it! I have always liked the unusual. One of my engagement rings was made of black gold and held an upside down black diamond. I much prefer this kind of ring to the traditional ones which are all about cut, colour and (often) outdoing everyone else.
This ring is described thus:
Unusual different and unique rough diamond ring solid 18k yellow gold set with rough diamond around 4.00ct (Ring model Nr. R-676)
