The main thing that you must consider while choosing such engagement rings is obviously the type of side stones. Note that you must always choose diamond accents that do not overpower the beauty of the main gemstone. After all, the center diamond is regarded as the symbol of your relationship with your partner.   When it comes to the appeal of your diamond accents, the best option is to choose the diamonds with the same brilliance, color, size, and clarity as that of your center diamond in order to attain consistency. In the case you prefer to highlight your main gemstone, you may go for accents of different color, size, and clarity. It is recommended to take suggestions from a professional as well while adding side stones to your diamond engagement rings. In fact, it is better to take suggestions from more than two diamond ring designers since the viewpoint and aesthetic skills of all the jewelers will not be the same. So, consulting a couple of diamond ring experts will let you choose the best option.
