Make your ring meaningful
While it is true that engagement rings are valuable because they are made with precious materials like gold, silver, platinum, diamonds and gemstones, the sentimental value they embody often far exceeds their monetary value. For that reason it is important that you give extra consideration to making the ring as meaningful as possible by matching the style to the prospective bride.
If a big stone is important to her, for example, then you may want to focus on getting the largest one you can afford.
Take a look at designer settings
If you know that she would like something other than a simple four-prong setting then you might consider looking at designer settings.
Find the perfect engagement ring
She may prefer a white metal or want the engagement ring to match the wedding band. As you can see, the options are quite varied. With a little research on your part, you should be able to come up with the "perfect" engagement ring for your bride-to-be.
Consider Your Budget
As you are probably well aware, the most important consideration is your budget. In this regard you have to proportion the budget between the diamond and the ring in which it is set. For example, you might want to choose a simple mounting in 14kt gold and the biggest and best diamond you can afford or you might opt for a smaller diamond with a more elaborate platinum setting with diamond accent stones to enhance the center stone beauty and durability. Fortunately, the range of choices is so vast that almost anyone can find something within their budget. Here are some factors to consider.
