About this 2.5ct natural marquise diamond

This 2.5ct natural marquise sits in the two to three carat band, graded K colour (faint-tinted) and VS2 clarity (very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5566550316. Listed at 14 retailers as of November 5, 2026, with prices from $22,606 to $40,524, a $17,918 spread on the same certified stone. With Clarity lists it at $40,524. 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.
