FAQs

SI1 means 'Slightly Included 1,' with inclusions visible under magnification. At 3 carats, SI1 in an emerald cut almost always shows visible inclusions. The step faceting's broad, transparent planes provide no concealment. The emerald cut at 3 carats is the worst shape-size combination for SI clarity grades.
Generally not. The emerald cut's step faceting provides zero inclusion concealment, and at 3 carats, the large transparent planes clearly display SI1 inclusions. This is the highest-risk standard clarity and shape combination at this size. Consider VVS-VS1 for emerald cuts at 3 carats.
The emerald cut's step facets create broad, transparent windows. Unlike brilliant cuts that scatter light to hide inclusions, step cuts show everything. At 3 carats, these windows are large enough to clearly display SI1 inclusions. This combination produces the most visible inclusions of any standard shape-grade-size configuration.
When looking for 3 carat natural diamonds, look between 2.9 to 3.3 carats so that you give yourself the best selection which will help find the best value. Searching within this range across different SI1 clarity options gives you the widest selection to compare cut quality, clarity grades, and overall value. A well-chosen 3 carat SI1 emerald natural diamond at the lower end of this range can look identical to one at the exact 3 carat mark while costing less.
