About this 2ct natural marquise diamond

This 2ct 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 2566188431. Listed at 13 retailers as of November 4, 2026, with prices from $20,543 to $31,784, a $11,241 spread on the same certified stone. Helzberg Diamonds lists it at $31,784. 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.
