About this 1.51ct natural marquise diamond

This 1.51ct natural marquise sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI 839695426. Listed at 9 retailers as of October 30, 2026, with prices from $5,846 to $12,805, a $6,959 spread on the same certified stone. NZ Jewellers lists it at $12,805. 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.
