Our metal register covers help transform a rooms appearance with minimal effort. They are designed to sit on top of the floor and can be held down by screws. The registers are black painted, this finish gives a protective coating that will resist staining or corrosion. With a 1/16 in. thickness and a well-defined cut, these registers will not only last a lifetime but will also enhance the look of any room. For an even more enhanced look, the customer can route out their hardwood floor by 1/16 in. so the vent will sit flush with the floor as you can see in some pictures. As the name describes it, this beautiful design shows the different shapes that a precious stone can have. Utilizing different shapes, symmetrically laid out all together, they become a group of jewels.
