Old Mine vs Antique Cushion Cut

Welcome to The Clear Cut Classroom, where we take deep dives into all things diamonds (and jewelry)! In this episode we talk about the differences between Old Mine and Antique Cushion cuts. Are these cuts right for you?

Watch the full video below!


There is always a lot of confusion between the two cuts and today, I'll break it down… it’s really simple! An old mine IS an antique cushion because it is an antique version of what has evolved into  today’s modern cushion (brilliant and modified brilliant). That being said, an old mine does have some key characteristics. Old mines have chunky facets, small table facets, the presence of a culet and a steep crown angle. 

In order to be considered a true old mine, the diamond has to have very specific measurements ex: under 53 table percentage, and more! If your diamond is just outside of the specific ranges, then it is technically an old mine, but if it has all of the other characteristics, it will be considered an antique cushion cut. 

To be considered an antique cushion cut, there needs to be the presence of a culet, chunky facets and a small table. You can have an antique cushion that falls under the brilliant category or it can fall into a cushion modified brilliant (if the faceting pattern is different from its classic counterpart)!

All in all, it comes down to preference. If you want that antique look, you can go for an old mine, or an antique cushion. The paperwork doesn't matter. All that matters is what you like!
