On the other hand, an antique diamond ring is something that ages more than 100 years. Note that some vendors tend to name any ring that is more than 20 years to be antique in order to show that it belongs to an old era. So, it is really important to know the age of a ring in order to determine whether it is vintage or antique.   It is quite natural for you to get confused about whether to buy a vintage diamond ring or an antique one. Oftentimes, it would be a wise option to buy a vintage diamond ring because the price range of a ring tends to increase with its age, and hence, the antique diamond rings will be really expensive. Yet the sad part is the quantifiers that used to determine the quality of a century-old diamond ring may not be the same now. So, there is no guarantee that you will get at least the half of what you spend on an antique ring when you sell or exchange it.
