The term black diamond engagement rings seems to be a contradiction of sorts because most women associate traditional engagement rings with white diamonds. White in this sense represents purity just the way a white wedding dress does for the bride. You would be hard pressed to find brides to be contemplating the thought of showing up on their wedding day in a black wedding dress. Yet, black diamonds have shown up quite often as the important center stone in diamond engagement rings and this seems quite acceptable.
An engagement ring with black diamond side stones cdould also be referred to as a black diamond engagement ring even though the larger center stone might be a white diamond. But most often the term refers to an engagement ring with a black center diamond.
Cost is factored heavily into the decisopn to get a black diamond because large black diamonds of a carat or more are typically less than 20% of the cost of a similarly sized white diamond. The exception to this is when the center black diamond happens to be a fine specimen of the carbonado natural black diamond that typically comes from Brazil. This type of black diamond that is untreated and exprtly faceted can run more in price than a white diamond of the same size. However the inexpensive black damond engagement rings that you see available will be the irradiated kind. Diamonds that are highly included (and therefore cheap)are good candidates for this procedure since the they become a dark inky green color that appears black and hides their rather visible imperfections. Thus they become transformed into a salable black diamond at a reasonable price.
Apart from low price there is the stylistic element of contrast that a center black diamond brings to the overall look of the engagement ring. Many brides to be find this look to be immensely appealing. They find the look fresh and different and they are still able to refer to their engagement ring as a diamond engagement ring. Also,if they have a favorite engagement ring designer, they can still get say a Tacori semi mount with pave diamonds and mount a loose black diamond in the center.
