About this 1.51ct natural oval diamond

This 1.51ct natural oval sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI 485155663. Listed at 16 retailers as of October 31, 2026, with prices from $7,275 to $16,046, a $8,771 spread on the same certified stone. NZ Jewellers lists it at $16,046. 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.
