5 Carat Old Mine Marquise SI1 Diamonds

At 5 carats, SI1 inclusions may be visible to the naked eye depending on the type and placement. The old mine marquise's broad, open facets offer less concealment than brilliant cuts, so carefully review imagery to ensure the inclusion is positioned where it is least noticeable.

SI1 offers significant savings compared to VS grades and above, which can be redirected to a higher color grade or larger carat weight. If you select a stone where the inclusion sits near the edge or under a prong, a 5 carat SI1 old mine marquise can look remarkably clean.

SI1 clarity is in many brilliant cuts eye-clean in old mine marquise cut diamonds. Inclusions noticeable under 10x magnification, sometimes visible to the naked eye depending on the cut. At 5 carats, the larger face can make inclusions slightly more visible than at smaller sizes. The old mine marquise cut's antique brilliant faceting helps mask minor inclusions.
