About this 2.51ct natural cushion diamond

This 2.51ct natural cushion sits in the two to three carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6541846766. Listed at 10 retailers as of October 30, 2026, with prices from $21,820 to $30,412, a $8,592 spread on the same certified stone. GemTrove lists it at $30,412. 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.
