The octagon cut of gemstones, also known as the "emerald octagon", is not as well-known as some of the more traditional cuts like round or princess. Its history is not well-documented but it's believed to have been developed more recently, in the 21st century by cutting experts looking to create something new and exciting.
What sets the octagon cut apart is its eight-sided shape giving it its octagonal appearance, and its step-facet pattern. Which is specifically designed to maximize the brilliance and fire of the gemstone making it truly sparkle in a way that other cuts cannot replicate.
As the octagon cut is relatively new, it's not as popular as some of the more traditional cuts, but it's starting to gain recognition among jewelry enthusiasts and experts who appreciate its unique look. Octagon cut is considered an alternative option for those who want something a bit different than the classic round or cushion cuts.
One of the main advantages of the octagon cut is its ability to create a visually striking look that sets it apart from traditional cuts. Additionally it also does a great job of highlighting the natural color and clarity of the gemstone.
