Round brilliant cut is the traditional favorite for engagement rings. The reason is obvious as well. Whoever loves the sparkle and the brilliance of a traditional round cut diamond will obviously choose these diamonds for their rings. Although other cuts are becoming popular quickly, none is yet popular enough to challenge the supremacy of round brilliant cut diamonds, for engagement or wedding rings.
People who love to stay classic, who don't like to compromise in style will surely choose round brilliant cut for themselves. This shape is absolutely perfect for solitaire or single stone. It can also be placed with other stones to create an amazing effect. On any precious metal, silver, gold, platinum or white gold, this cut is a marvel to have. However, most people don't go for silver while buying diamond engagement rings.
Round brilliant cut is one of the oldest cuts of diamonds and thus you can find a diamond of this shape well inside your budget. This is not true with more modern cuts which are complex and cost more. Sometimes, these modern cuts are just an amalgamation of two different traditional cuts and thus cost a lot more due to the complexity of performing that cut.
However, round brilliant cuts might become expensive as you go for bigger stones. In the round brilliant cut, the wastage of the stone while performing the cut is high. Thus, in bigger stones, this becomes a factor which increases the cost. Although, if you are buying a round brilliant cut diamond engagement ring, it is a onetime purchase, in most probability, and you might not think too much about the cost.
Furthermore, as there is a lot of polishing done on this stone, it is always easy to hide any flaws of the original stone. That is another reason why the jewelers have preferred this cut for decades now. As the base of the ring covers a lot of this stone, it is easy to hide any imperfections on the base of the stone as well. Nobody can know that the gorgeous stone you have in the wedding ring has a tiny flaw somewhere and didn't cost you much!
Finally, the setting on the ring can be diverse as well. You can go for solitaire, pave and other settings while choosing the design of the ring. The elegant and dazzling look of round brilliant cut rings can make your engagement ring truly classic.
