It will be really easier for you to check the quality of a diamond in this case because many simple tests such as fog test, water test, newspaper test, etc., are easier to do on individual diamonds. Moreover, the chances for you to bargain for diamonds are more here.
One of the best options for purchasing affordable diamonds is to purchase it from wholesale dealers. Yet note that the chances for you to get a diamond from wholesale dealers will be really low unless you know the seller in person or you are in a respectable position. Otherwise, you can opt to buy a number of diamonds that you can encrust on the diamond bands of both the bride’s and the groom’s diamond rings.
Regardless, you need to choose diamonds that offer a good cut quality; you may compromise on the clarity grade and color of your diamonds if you have a limited budget. However, make sure that the gemstone that you choose is visibly flawless and colorless. Of course, the appeal of your diamonds will be enhanced once it is set on a precious metal.
