About this 2.51ct natural marquise diamond

This 2.51ct natural marquise sits in the two to three carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2544662197. Listed at 4 retailers as of October 30, 2026, with prices from $32,979 to $38,398, a $5,419 spread on the same certified stone. 77 Diamonds lists it at $38,398. 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.
