This 0.51ct natural marquise sits in the half to three-quarter carat band, graded J colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI 815636590. Listed at 13 retailers as of October 30, 2026, with prices from $446 to $2,262, a $1,816 spread on the same certified stone. NZ Jewellers lists it at $2,262. 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.
