A bevel is simply a sloped surface. This simple yet ingenious design is commonly used for various items in stone or construction work. Bevels have been around for quite a long time, and while there is no decisive documentation that states when exactly this practice first started, mirrors with beveled edges that date all the way back to the 16th century exist. The style had become increasingly popular towards the 19th century and had reached its peak in the 1890s, as beveled glass was widely embraced in American architecture, design, and art. It is no surprise that the trend has carried over to other various industries, including in traditional metal rings.
Bevels serve more purpose than just aesthetics. When it comes to stone and construction work, bevels are used to not only soften sharp edges for safety and wear resistance, but also make putting other pieces together significantly easier and more secure, almost like a puzzle piece!
