Since it plays a major role in terms of emotional and financial aspects, you will have to secure it to the best. However, you must also make sure that you are getting the best diamond for your dollar. Diamond rings will be usually very expensive, but you can trim down the price of diamond engagement rings if you played smartly. Obviously, the main thing that affects the diamond ring cost is the gemstone; so choose a diamond that offers a good shine but at an affordable price. One of the best examples for this is an emerald cut diamond that offers a decent shine at a comparatively affordable price range. Options like a square cut diamond and oval shaped diamonds are also considerable ones. The next thing that affects the price of diamond engagement rings is its metal settings. You need to choose an engagement ring that employs less amount of metal. A prong setting or tension setting will be ideal for this; the diamond ring cost will be relatively more for options like a bezel set and a channel set ring. Similarly, the type of designs and patterns employed in your ring will also affect the price of your diamond engagement rings. So, it is better to go for simple and plain designs for affordable purchase.
