Invented in the early 20th century by the Asscher Brothers of Holland, the Asscher cut features a square shape with a flat table (top surface), many small step cuts along the top edges, and longer facets underneath for a Hall of Mirrors effect. Like the Cushion cut, the Asscher cut has an open culet (the bottom of the gemstone) and a facet plan that draws the eye into the gemstone and gives it depth. This is a highly unusual design, often favored by individuals with a more modern sense of style.

- The Assure cut is exquisite in height and colors. My sister has that cut and is still asked how expensive the diamond is as it's flawless with clarity and color of rainbow sparkles as it captures everyone's attention!
- My fiancé bought me the 1.24 size in this stone. I love it! I worked in jewelry for 5 years so I was very skeptical but a real stone with this quality and size would have cost $15,000 which is crazy. Nobody can tell it's not natural! I took it intoy old jewelry store to have it set into my ring and they had no idea! Everyone was in awe of how beautiful my stone is. I couldn't be happier! I've only been wearing it a week and I've alteady gotten so many compliments on it! Thanks diamond nexus!
- This stone is gorgeous, and you cannot tell it is not a diamond with the naked eye. It even has the fire of a diamond. I'm not necessarily trying to fool anyone; I just wanted something "glassy" with fire and almost as hard as a diamond (so it will last) but without the huge price tag. My only concern and the reason I gave it four stars is I've only had this stone for a few weeks, and I cannot give it 5 stars until I see how it handles over time. Ask me for another review in 10 or so years!
