About this 0.51ct natural oval diamond

This 0.51ct natural oval sits in the half to three-quarter carat band, graded I colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI 670456374. Listed at 15 retailers as of November 5, 2026, with prices from $848 to $3,500, a $2,652 spread on the same certified stone. NZ Jewellers lists it at $3,500. 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.
