About this 2.51ct natural oval diamond

This 2.51ct natural oval sits in the two to three carat band, graded K colour (faint-tinted) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2277905783. Listed at 7 retailers as of November 6, 2026, with prices from $9,761 to $17,543, a $7,782 spread on the same certified stone. Yorxs lists it at $17,543. 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.
