Asscher Diamond Questions
What clarity should I choose for an asscher cut?
Like an emerald cut, an asscher's step-cut facets show more of the inside of the stone, so many buyers choose VS2 or better and check the photos to confirm it looks clean.
What is the difference between an asscher and an emerald cut?
Both are step cuts with cropped corners. An asscher is square, while an emerald cut is a longer rectangle.
Can I set a loose asscher diamond in an engagement ring?
Yes. Book a video or phone appointment and we will help you pair it with one of our settings. Loose diamonds are final sale, so we are glad to help you choose first.
