Below are some of the tips that you can follow while purchasing your engagement diamond rings. Consider the Metal Choice Even though it is really expensive, most people rush for platinum metal because of its hardness, hypoallergenic nature, and mirror-like reflection; this is an ideal choice if your budget range is huge. Otherwise, go for palladium or gold metal, which are also hard, lustrous, and hypoallergenic too, but being comparatively cheaper. Avoid Whole Carats Price of diamonds is always high for the whole carat. So, instead of choosing a single diamond of huge carat weight, choose many diamonds and set them in a cluster or halo in order to create an illusion of single huge diamond. Besides, you can always choose 0.96 or 1.45-carat stones to cut the costs. Upgrade your Ring Later Be flexible with your selection range, as you have the option to upgrade your engagement diamond ring whenever you desire. So, try to choose a ring with simple settings or smaller diamonds so that you can have a hold on the budget.
