About this 2.51ct natural oval diamond

This 2.51ct natural oval sits in the two to three carat band, graded I colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI 766663456. Listed at 14 retailers as of October 30, 2026, with prices from $18,710 to $30,445, a $11,735 spread on the same certified stone. NZ Jewellers lists it at $30,445. 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.
