1 Carat Asscher Cut SI1 Lab Grown Diamonds

SI1 inclusions are visible in some 1 carat asscher lab diamonds but not all. 1 carat lab grown diamonds are a great starting point and were the average diamond size for many decades before lab diamonds came around. The asscher cut's step-cut faceting can reveal SI1 inclusions more readily because the open facets act as a window into the stone. Individual stone inspection is recommended to confirm eye-clean quality at this grade.

Focus on inclusion placement. In a asscher cut, inclusions beneath the center table are most visible because the step-cut facets create clear windows into the stone. Inclusions along the edges or corners are far less detectable. White or transparent inclusions are preferable to dark crystals. If you cannot inspect the specific stone, stepping up to VS2 guarantees an eye-clean result.

SI1 can be an excellent value play for a 1 carat asscher lab diamond when you select the right stone. An eye-clean SI1 asscher saves 15% to 25% compared to VS2 while delivering identical visual results. A value-focused choice that can save 15% to 25% when you find an eye-clean stone. The key is individual stone selection, since not every SI1 asscher will be eye-clean at this grade.

SI1 clarity is in many brilliant cuts eye-clean in asscher cut diamonds. Inclusions noticeable under 10x magnification, sometimes visible to the naked eye depending on the cut. At 1 carats, the stone size keeps inclusions manageable. For this step-cut shape, risky in step cuts where the transparent facets may reveal inclusions to the naked eye.
