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 VS2 clarity (very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1242018405. Listed at 8 retailers as of November 3, 2026, with prices from $13,600 to $26,381, a $12,781 spread on the same certified stone. NZ Jewellers lists it at $26,381. 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.
