When making a purchase as important as a ring, the customer should expect to closely analyze various facets of the production process - ones that will inevitably inform their final decision. To begin with, observe the thickness of the ring, the metal being used and the way the side and center stones are set. It also helps to view the diamond with your naked eye - first in both natural and artificial light and then through a loop microscope. Finally, be sure to look over the certification provided with the diamond, as well as its specific characteristics.
Of course, with all the major observations present during the buying process, there are often several small aspects sometimes forgotten along the way that potentially make or break a ring choice. For example, be sure to examine your ring when it is set and finished; check the craftsmanship of the ring when it is fully completed to make sure that it is up to high standards - to see if the center stone of the diamond is set level. Moreover, don’t forget to ask about the warranty provided with the ring and what it does and does not cover. Finally, after you propose, have your fiance try the ring on when their hands are both hot and cold to test if the ring still fits properly.
