The first thing to think about is the metal choice to style an eternity ring. It is better to go for a platinum metal in this case because of the supreme qualities that it boasts. For instance, consider its hardness, luster, durability, resistance to stain, hypoallergenic nature, etc. To top it up, there are many designs available for platinum diamond eternity rings as well in the jewelry stores.
One of the commonly used designs for platinum diamond eternity rings feature a platinum band that is entirely paved with melee diamonds. You can also elevate the design by including any of the colorful gemstones such as rubies, emeralds, sapphires, etc.
In case you prefer to show off something offbeat, a half eternity diamond ring will be a great option. Here, gemstones of various shapes and size are displayed on a band up to the visible area. This is also an affordable option since the number of gemstones used here is comparatively less.
