About this 2ct natural marquise diamond

This 2ct natural marquise sits in the two to three carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1565629325. Listed at 5 retailers as of November 5, 2026, with prices from $12,658 to $15,867, a $3,209 spread on the same certified stone. Blue Nile lists it at $15,867. 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.
