FAQs

SI1 means 'Slightly Included 1,' with inclusions visible under magnification and sometimes to the naked eye. At 3 carats, SI1 in a princess cut carries more visibility risk than at smaller sizes. The princess cut's brilliant faceting helps, but the larger face-up area means more careful selection is needed.
Some SI1 princess cuts at 3 carats are eye-clean, especially with favorably positioned inclusions. The brilliant-style faceting provides reasonable concealment. However, the larger face-up area means the success rate is lower than at 1-2 carats. Focus on stones with edge-positioned inclusions for the best odds.
SI1 at 3 carats is a budget-focused choice that requires selective shopping. The savings are very significant at this size. The princess cut's sparkle gives you better odds of eye-clean results than step cuts. Verify each stone individually, and look for inclusions near corners rather than under the table.
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 princess natural diamond at the lower end of this range can look identical to one at the exact 3 carat mark while costing less.
