About this 1.72ct natural marquise diamond

This 1.72ct natural marquise sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1557150681. Listed at 8 retailers as of October 30, 2026, with prices from $9,989 to $15,789, a $5,800 spread on the same certified stone. NZ Jewellers lists it at $15,789. 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.
