About this 0.9ct natural marquise diamond

This 0.9ct natural marquise sits in the just-under-one-carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6441120990. Listed at 13 retailers as of November 1, 2026, with prices from $2,626 to $7,524, a $4,898 spread on the same certified stone. Moon Ocean lists it at $7,524. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
