About this 2.5ct natural marquise diamond

This 2.5ct natural marquise sits in the two to three carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1555701678. Listed at 7 retailers as of October 31, 2026, with prices from $24,880 to $38,814, a $13,934 spread on the same certified stone. MOH London lists it at $38,814. 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.
