About this 1.31ct natural marquise diamond

This 1.31ct natural marquise sits in the one-and-a-quarter to one-and-a-half carat band, graded I colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1559733370. Listed at 5 retailers as of November 5, 2026, with prices from $10,428 to $17,441, a $7,013 spread on the same certified stone. NZ Jewellers lists it at $17,441. 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.
