About this 1.51ct natural marquise diamond

This 1.51ct natural marquise sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5566688371. Listed at 7 retailers as of October 30, 2026, with prices from $5,200 to $9,725, a $4,525 spread on the same certified stone. NZ Jewellers lists it at $9,725. 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.
