About this 1.25ct natural marquise diamond

This 1.25ct natural marquise sits in the one-and-a-quarter to one-and-a-half carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6551400616. Listed at 22 retailers as of November 1, 2026, with prices from $8,048 to $17,069, a $9,021 spread on the same certified stone. NZ Jewellers lists it at $17,069. 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.
