There are many things, which you must keep in mind at this point in time, the most important one being your budget.         It is to be noted that you will have to take many financial responsibilities in the near future such as hosting the engagement party, wedding planning, buying or renting a new house, and many more. Hence, it is not a good decision to spend your life savings on your diamond engagement rings. Besides, there are many low-cost diamond engagement rings available in the market, which can even beat most of the extravagant diamond ring designs. One of the popular options available for affordable diamond rings is going for a cluster diamond ring design. Here, a set of tiny diamonds will be tightly clustered at the center of a ring in order to create the illusion of a big solitaire when viewed from a distance. Note that this will be way too cheap when compared to a solitaire diamond ring of similar carat weight. In fact, you may add or reduce the number of diamond accents here according to your budget.
