About this 2.5ct natural oval diamond

This 2.5ct natural oval sits in the two to three carat band, graded J 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 7563550306. Listed at 16 retailers as of October 30, 2026, with prices from $20,825 to $37,320, a $16,495 spread on the same certified stone. With Clarity lists it at $37,320. 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.
