How a asscher is graded

Lab-grown asscher diamonds are graded on the same 4C scale as every other diamond — carat, color, clarity, and cut. Cut grading for fancy shapes assesses face-up appearance, facet arrangement, and light performance. Asscher stones with good proportions are scarce relative to demand, which affects both price and availability.

Price and what to expect

Asscher cuts are among the rarest, so they carry a high premium over rounds. Their distinctive concentric facets create a strong geometric signature that is hard to replicate with another cut.

Where to spend and where to save

Spend on clarity above all. The step-cut pattern and broad open center show inclusions clearly, and the geometry is unforgiving. VS2 or better, ideally VS1.

For any shape, checking the grading report is non-negotiable. Read how to verify a diamond certificate and confirm the report number with the laboratory directly before you commit.

Settings that suit a asscher

Asscher diamonds have an elongated outline, so the setting shape matters as much as the metal. Solitaire and bezel settings protect the points of the stone most effectively, which is a practical consideration for any shape with vulnerable corners. Halo and pavé settings add light but can visually shorten an elongated outline — a common problem people bring back to us after seeing a ring in person.
